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

A pool has a walkway around it that is a width of 4 1/2 feet all the way around! The length is 100 feet and the side length is 30 feet, what is the area of the walkway? Work must be shown if there is more than one answer. :)
Answer: OK two different answers.
If the dimensions of the pool are 100 × 30, and the sidewalk is outside that, the area of the sidewalk is 1251 square feet.
If the outside dimensions of the sidewalk are 100 × 30, and the pool is inside that, the area of the sidewalk is 1089 square feet.
Step-by-step explanation: Solution #1: Sidewalk outside 100×30 pool.
The sidewalk is 4 1/2 feet wide, so twice as wide all together.
The outside ends of the sidewalk are added to the pool dimensions.
100 + 9 = 109 30 + 9 = 39
The overall area: Multiply 109 × 39 = 4251 ft²
Find the area of the pool 100 × 30 = 3000 ft²
Subtract the area of the pool from the overall area 3000 - 2451 = 1251
1251 square feet is the area of this sidewalk
Solution #2: Pool inside 100×30 sidewalk.
The sidewalk is 4 1/2 ft wide so the pool will be 9 feet shorter in length and width,
100- 9 = 91 and 30 - 9 = 21 The area of this pool is 91 × 21 = 1911 ft²
The overall area is 100 × 30 = 3000 ft²
Subtract the pool's area from the overall area
3000 - 1911 = 1089
The area of this sidewalk is 1089 square feet

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]

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
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

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
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.
Emily is solving the equation 2(x+9)=4(x+7)+2. Her step are shown.
Click on the first step in which Emily made an error.
A. Step 1: 2(x+9)=4(x+7)+2
B. Step 2: 2x+18=4x+28+2
C. Step 3: 2x+18=4x+26
D. Step 4: -8x=2x
E. Step 5: -4=x
Also explain why answer B is wrong. <3
Answer:
C. Step 3: 2x + 18 = 4x + 26
Step-by-step explanation:
Step 1: Write equation
2(x + 9) = 4(x + 7) + 2
Step 2: Solve for x
Distribute: 2x + 18 = 4x + 28 + 2Combine like terms: 2x + 18 = 4x + 30Here we see that Emily made a mistake here. Instead of adding 2 to 28 and getting 30, Emily subtracted 2 from 28 to get 26. Hence, our answer should be C.
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

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)
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]
