Ivan works as a tutor for $8 an hour and as a waiter for $7 an hour. This month, he worked a combined total of 89 hours at his two jobs. Let t be the number of hours Ivan worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.
Answer:
t+623
Step-by-step explanation:
If t is the number of hours Ivan worked as a tutor this month, you can say that the number of hours that Ivan worked as a waiter would be the result of subtracting the amount of hours he worked as a tutor this month from the combined total of hours he worked, which is:
89-t
After this, you can say that the combined total dollar amount Ivan earned this month is the result of adding up what he earned as a tutor plus the amount he earned as a waiter which is equal to 89-t. So, you would have:
8t+7*(89-t)
=8t+623-7t
=t+623
This means that the expression for the combined total dollar amount he earned this month is: t+623
f(n)=2n + 4 find the inveres
Answer:
y = 1/2x - 2 OR f(n)= 1/2n - 2
Step-by-step explanation:
Start by rewriting with X and Y just for ease:
Swap X and Y's places
Solve for Y
y = 2x+4
x = 2y+ 4
x - 4 = 2y
1/2x - 2 = y

Which is the factor of 15xy-45x-6y+18?
Answer:
3 (5 x - 2) (y - 3)
Step-by-step explanation:
Factor the following:
15 x y - 6 y - 45 x + 18
Hint: | Factor out the greatest common divisor of the coefficients of 15 x y - 6 y - 45 x + 18.
Factor 3 out of 15 x y - 6 y - 45 x + 18:
3 (5 x y - 2 y - 15 x + 6)
Hint: | Factor pairs of terms in 5 x y - 2 y - 15 x + 6 by grouping.
Factor terms by grouping. 5 x y - 2 y - 15 x + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):
3 y (5 x - 2) - 3 (5 x - 2)
Hint: | Factor common terms from y (5 x - 2) - 3 (5 x - 2).
Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):
Answer: 3 (5 x - 2) (y - 3)
A scale drawing of an office space uses a scale of 2 in. : 3 yd. The scale drawing has an area of 12 square inches. What is the area of the actual office space?
Answer: The area of the actual office space = 18 sq. yards
Step-by-step explanation:
Formula : Image length = Scale factor x original length
Given: A scale drawing of an office space uses a scale of 2 in. : 3 yd.
i.e. scale factor = [tex]\dfrac23[/tex]
The scale drawing has an area of 12 square inches.
i.e. [tex]\text{12 sq. inches}=\dfrac23\times\text{area of the actual office space }[/tex]
[tex]\Rightarrow\ \text{Area of actual office space}=\dfrac{3}{2}\times12=18\text{ sq. yards}[/tex]
Hence, the area of the actual office space = 18 sq. yards

x varies directly with y and inversely with [tex]z^{2}[/tex]. If x = 3 and y = 12 when z = 2, find y when x = 1 and z = 4.
Answer:
16
Step-by-step explanation:
x∞y/z²
x=ky/z²(where k is the constant)
3=12/2²k
3=12/4k
3=3k
3÷3=k
therefore k=1
x=1y/z²
making y the subject
xz²=y
1(4²)=y
1×16=y
16=y
Clarissa wants to see Luke Bryan in concert. Tickets cost $54.50 each. She has already saved $25 and is going to save $5 per week from her allowance. The inequality 25 + 5w ≥ 54.50 can be used to determine the number of weeks, w, Clarissa will need to save in order to be able to have at least enough money buy a ticket to the concert. Which statement about the number of weeks that Clarissa has saved is true?
Answer:
The minimum number of weeks Clarissa needs to save is 6 weeks.
Step-by-step explanation:
Clarisaa wants to go to the concert with the luke bryan
Ticket cost=$54.50
Inequality= 25+5w[tex]\geq[/tex] 54.50
upon solving the inequality we get
5w [tex]\geq[/tex] 54.50-25
5w [tex]\geq[/tex] 29.5
w [tex]\geq[/tex] 5.9 = 6weeks approximately
so The minimum number of weeks clarissa needs to save is 6 weeks

Nick has two pieces of twine.One 20 feet long and the other one 12 feet long.If he wants cut them up to produce many pieces of twine that are all of the same length with no twine left over what is the greatest length in feet that he can make them?
Answer:
The greatest length in feet the twines can be cut into with no twine left over is 4 feet
Step-by-step explanation:
To determine the greatest length a 20 feet long twine and a 12 feet long twine can be cut into such that the pieces are of the same length and no twine is left over, we will find the highest number that can be used to divide 20 and 12 with no remainder. Hence, we will find the Highest common factor (HCF) of 20 and 12.
Factors of 20 are: 1,2,4,5,10, and 20
and the factors of 12 are: 1,2,3,4,6, and 12
The highest common factors of 20 and 12 is 4.
Hence, the greatest length in feet the twines can be cut into with no twine left over is 4 feet.
Move the numbers to the blanks to order them from least to greatest value.

Use the distributive property to write two equivalent expressions for 6 x 53
Answer:
a. (6 * 50) + (6 * 3)
b. (6 * 40) + (6 * 13)
Step-by-step explanation:
Here, we want to use the distributive property to write equivalent expression .
We can have the given expression as follows;
6 * ( 50 + 3) = (6 * 50) + (6 * 3)
Furthermore, we can write the expression as;
6 * (40 + 13) = (6 * 40) + (6 * 13)
Is 80/10 equal to -8
Answer: No
Step-by-step explanation: Two positives divided never make a negative
Answer:
No, 80/10 turned into a whole number is 8, not -8.
Step-by-step explanation:
To get a whole (1), you need to have 10/10. Since we have 10/10 8 times (80/10) this means we get a whole number of 8, not -8. Therefore, its false. 80/10 is NOT equal to -8
help me solve the problem it 2 problems they all in together
Answer:
x = 10
x = 27
Step-by-step explanation:
53 and 5x + 3 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
53 = 5x + 3
subtract 3 from both sides of the equation
53 - 3 = 5x + 3 - 3
50 = 5x
divide both sides of the equation by 5
50/5 = 5x/5
10 = x
82 and 3x + 1 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
82 = 3x + 1
subtract 1 from both sides of the equation
82 - 1 = 3x
81 = 3x
divide both sides of the equation by 3
81/3 = 3x/3
27 = x

Emmanuel is starting a cycling training program. He will start cycling a short distance and increase his distance over time. Emmanuel will cycle 5 miles during the first week and increase his distance by 2 miles each week for 12 weeks.
Answer:
29milesStep-by-step explanation:
We can use the equation of a straight line as a concept to solve this problem
that is y=mx+c
at the end of the 12 weeks we can estimate the total distance that Emmanuel must have covered.
Given data.
the total distance is y
the number of weeks is x
and the starting distance is c (based on the equation of line)
starting distance= 5 miles,
increment = 2miles each week
number of weeks =12
substituting we have
y=2(12)+5
y=24+5
y=29miles
the total distance covered after 12 weeks is 29miles
According to Teo's bread recipe, he should bake the bread at ° for 30 minutes. His oven measures temperature in °F. To what temperature, in °, should he set his oven? Rewrite the formula C= 59 F-32 to find the Fahrenheit temperature that is equal to °C.
Answer:
[tex]F = \frac{9}{5}(C + 32)[/tex]
Step-by-step explanation:
Given
[tex]C = \frac{5}{9}F - 32[/tex]
First, we need to solve for F
[tex]C = \frac{5}{9}F - 32[/tex]
Add 32 to both sides
[tex]C + 32 = \frac{5}{9}F - 32 + 32[/tex]
[tex]C + 32 = \frac{5}{9}F[/tex]
Multiply both sides by [tex]\frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = \frac{5}{9}F * \frac{9}{5}[/tex]
[tex]\frac{9}{5} * (C + 32) = F[/tex]
[tex]F = \frac{9}{5} * (C + 32)[/tex]
[tex]F = \frac{9}{5}(C + 32)[/tex]
Next, is to determine the temperature in degrees Fahrenheit
However, this is not stated the degree Celsius equivalent is not stated in your question.
So, I'll assume a value for it.
Assume that C = 23
Substitute 23 for C in [tex]F = \frac{9}{5}(C + 32)[/tex]
[tex]F = \frac{9}{5}(23+ 32)[/tex]
[tex]F = \frac{9}{5}(55}[/tex]
[tex]F = 9 * 11[/tex]
[tex]F = 99[/tex]
plz hlep ememmeememeemem me its a math ? need to do it
Answer:
Step-by-step explanation:
slope = M
M= rise / run
rise = Y2-Y1
run = X2 -X1
P1=(X1,Y1) = (3,-3)
P2=(X2,Y2) = (6,9)
M= 9-(-3) / 6-3
M=12 /3
M=4
the slope is 4
a parallel line will have the same slope
a perpendicular line will have an inverse slope or 1/4

Given that y is directly proportional to x.
[tex] \sf y \propto x[/tex]
[tex]\longrightarrow \sf y = k \times x[/tex]
[tex]\\[/tex]
At first, we must find the value of k.
We have a relation given between 'x' and 'y' (that is, when 'x' is 75, 'y' is 60). We can call that Case - 1.
[tex]\sf 60 = k \times 75[/tex]
[tex]\longrightarrow \sf k = \dfrac{60}{75}[/tex]
[tex]\longrightarrow \sf k = \dfrac{4}{5}[/tex]
[tex]\\[/tex]
Now, we have to find 'x' when 'y' is 480. We can call that Case - 2.
[tex]\sf y = k \times x [/tex]
We are having the value of 'y' and 'k'.
[tex]\longrightarrow \sf 480 = \dfrac{4}{5} \times x[/tex]
[tex]\longrightarrow \sf x = 480 \times \dfrac{5}{4}[/tex]
[tex]\longrightarrow \sf x = 120 \times 5[/tex]
[tex]\leadsto \underline{\boxed{\sf {\pink{x = 600}}}}[/tex]
