An Actor invest some money at 6% and $41000 more than twice the amount at 9% the total annual interest earned from the investment is $32490 how much did he invest at each amount use the 6 step method
Answer: he invested $120000 at 6% and $281000 at 9%
Step-by-step explanation:
Let x represent the amount invested at 6%
Let y represent the amount invested at 9%
The Actor invest some money at 6% and $41000 more than twice the amount at 9%. This means that
y = 2x + 41000- - - - - - - - - 1
The interest gotten from x is
6/100 × x = 0.06x
The interest gotten from y is
9/100 × y = 0.09y
The total annual interest earned from the investment is $32490. It means that
0.06x + 0.09y = 32490- - - - - - - - -2
Substituting equation 1 into equation 2, it becomes
0.06x + 0.09(2x + 41000) = 32490
0.06x + 0.18x + 3690 = 32490
0.06x + 0.18x = 32490 - 3690
0.24x = 28800
x = 28800/0.24
x = 120000
Substituting x = 120000 into equation 1, it becomes
y = 2(120000) + 41000
y = 281000
Carrie had $60. as an allowance for the week. She spent 2/5 of it on snacks, and 1/4 on stickets and saved the remainder. How much money did she save?
Answer:
$ 21
Step-by-step explanation:
Money spent = (2/5) * 60 + (1/4) * 60
= 2*12 + 1*15
= 24 + 15
= $ 39
Money save = 60 - 39 = $ 21

Answer:
(-1,1)
Step-by-step explanation:
The solution to the system of equations is where the two lines cross
They cross at x=-1 y=1
(-1,1)
Answer:
The answer is (-1,1)
Step-by-step explanation:
First of all, you can see where the two lines intersect.
Also, if there was no graph, then you could solve by substitution:
1. Substitute y from y = 2x + 3 to -x
2. Then simplify
-x = 2x + 3
subtract 2x from each side
-3x = 3
divide -3 from each side
x = -1
3. To solve for the value of y, you can plug -1 for x and solve.
y = -(-1)
y = 1

The sum of two numbers is 90, so this involves addition because the sum is the answer of an addition problem. x+y=90.
x is the larger number
y is the smaller number
The larger number is 14 more than or addition sign 3 times or multiplying the smaller number (y).
The equation would be x=14+3y because it is 3 times the smaller number.
Hope this helps!

(10 points) Joe’s parents bought him a new car for his birthday. They paid $6990 for a car that was originally priced at $7599. What percent of the original price did they pay?
[A] Set up a proportion that can be used to solve this problem.
[B] Show all steps to solve the problem.
HELP: Please and thank you!
Answer:
91.99%
Step-by-step explanation:
To find what percentage of $7599 is $6990, we simply need to divide $7599 by $6990 and multiply by 100:
6990 / 7599 * 100 = 91.99%
Therefore, they paid 91.99% of the original price.
1. Jayden spent $46.20 on 12 gallons of gasoline. What was the price per gallon? 2. Jayla buys 1.2 pounds of bananas. The bananas cost $1.29 per pound. To the nearest cent, how much does Jayla pay for the bananas? 3. Billy ate 1/4 of a pizza, and Wi ate 1/3 of the same pizza. How much of the Pizza did they eat in all?
Answer:
1. $3.85 per gallon
2. $1.59
3. 7/12
Step-by-step explanation:
1. Jayden spent $46.20 on 12 gallons of gasoline. The price per gallon can be gotten by dividing the total price paid by the total number of gallons bought:
46.20 / 12 = $3.85 per gallon
The price per gallon is $3.85
2. Jayla buys 1.2 pounds of bananas and they cost $1.29 per pound. The total amount paid for the bananas is:
1.2 * 1.29 = $1.59
3. Billy ate 1/4 of a pizza, and Wi ate 1/3 of the same pizza. The total fraction of the pizza ate is:
1/4 + 1/3 = 7/12
They ate 7/12 of the pizza
The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5 x plus 10 y equals 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total? 55 60 130 150
Answer:
150
Step-by-step explanation:
Step 1: Plug in what we know
5x + 10(5) = 800
Step 2: Solve for x (smaller cars)
5x + 50 = 800
5x = 750
x = 150
Answer:

What is the average rate of change between:
x= 1 and x = 2?
x = 2 and x = 3?
x = 3 and x = 4?
Answer: See bolded below
Step-by-step explanation:
Average rate of change is the slope. To find that, we would need the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Reminder: The scale fo the graph goes by 2. You need to make sure you are looking at the right coordinates.
1. The coordinate points are (1, 2) and (2, 4).
[tex]m=\frac{4-2}{2-1}=\frac{2}{1} =2[/tex]
The average rate of change is 2.
2. The coordinate points are (2, 4) and (3, 8).
[tex]m=\frac{8-4}{3-2} =\frac{4}{1} =4[/tex]
The average rate of change is 4.
3. The coordinates are (3, 8) and (4, 16).
[tex]m=\frac{16-8}{4-3} =\frac{8}{1} =8[/tex]
The average rate of change is 8.

What is the solution set of the given system?

[(5, 6)) [/13/5, 6/5) [[6/5, 13/5))
Answer:
([tex]\frac{13}{5}[/tex] , [tex]\frac{6}{5}[/tex] )
Step-by-step explanation:
Given the 2 equations
2x - y - 4 = 0 → (1)
3x + y - 9 = 0 → (2)
Adding the 2 equations term by term will eliminate the term in y, thus
5x - 13 = 0 ( add 13 to both sides )
5x = 13 ( divide both sides by 5 )
x = [tex]\frac{13}{5}[/tex]
Substitute this value into either of the 2 equations and evaluate for y
Substituting into (2)
[tex]\frac{39}{5}[/tex] + y - 9 = 0
- [tex]\frac{6}{5}[/tex] + y = 0 ( add [tex]\frac{6}{5}[/tex] to both sides )
y = [tex]\frac{6}{5}[/tex]
Solution is
([tex]\frac{13}{5}[/tex] , [tex]\frac{6}{5}[/tex] )

h(t) = -t + 3; Find h(-5)
Answer:
8
Step-by-step explanation:
h(t) = -t + 3;
h(-5)
Let t = -5
h(-5) = - -5 +3
= 5+3
= 8
Answer:
8
Step-by-step explanation:
h(t) = -t + 3
Put t as -5 in the function.
h(-5) = -(-5) + 3
The negative signs cancel.
h(-5) = 5 + 3
Add both the terms.
h(-5) = 8

Answer:
A) inside the circle
Step-by-step explanation:
equation of the circle is:
[tex](x-a)^{2} + (y-b)^{2} = r^{2}[/tex]
where (a,b) is center of the circle and r is radius so
[tex]x^{2} + y^{2} = r^{2}[/tex] now plug in given point to find the radius
[tex](6)^{2} + (-4)^{2} = r^{2}[/tex]
36 +16 = 52 so
r = [tex]\sqrt{52}[/tex] ≈ 7.2 or [tex]r^{2} =52[/tex]
when you plug point (√2 , -7) into equation of the circle
(√2)^2 + (-7)^2 = 2 +49 =51
51 is less than 52 so this is inside of the circle

Select values to multiply each equation by to form opposite terms for the x-variable. One-third x + one-sixth y = 2 One-half x + three-fourths y = negative 3
Answer:
First equation: 1/2
Second equation: -1/3
Step-by-step explanation:
We get the following equations:
[tex]\frac{1}{3}x+\frac{1}{6}y=2[/tex] first equation
[tex]\frac{1}{2}x+\frac{3}{4}y=-3[/tex] 2nd equation
Then, to obtain opposite terms for the x variable, we need to identify the coefficient of the x for the 1st equation and the 2nd equation as:
The coefficient for x in the 1st equation is [tex]\frac{1}{3}[/tex] and the coefficient for x in the 2nd equation is [tex]\frac{1}{2}[/tex]
Finally, we need to multiply 1st equation with the coefficient of the 2nd equation and multiply the 2nd equation with the negative of the coefficient of the 1st equation.
We multiply by the negative of the coefficient of the 1st equation because we need to find opposite terms for x.
So, the first equation is equal to:
[tex](\frac{1}{3}x+\frac{1}{6}y)*\frac{1}{2} =2*\frac{1}{2} \\\frac{1}{6}x+\frac{1}{12}y=1[/tex]
The second equation is:
[tex](\frac{1}{2}x+\frac{3}{4}y)*\frac{-1}{3} =-3*\frac{-1}{3} \\\frac{-1}{6}x+\frac{-1}{4}y=1[/tex]
Now, the coefficients for x, 1/6 and -1/6, are opposite terms.

The ratio of sandwiches with white bread to brown bread is 10:3. Out of the sandwiches that are white, 2 3 are vegetarian. Out of the sandwiches that are on brown bread, half are vegetarian. Wha
Answer:
Ratio of sandwiches with white bread and brown bread is 10:3. Of the white sandwiches 2/3 are vegetarian, of the sandwiches that are brown half are vegetarian. What fraction of the sandwiches are vegetarian?
Step-by-step explanation:
Givens
The ratio between white bread and brown bread is 10:3, that is, for every 10 white bread, there are 3 brown bread.
2/3 of white sandwiches are vegetarian.
1/2 of brown sandwiches are vegetarian.
We know that white bread is represented by 10, and brown bread is represents by 3. So, 2/3 of 10 are vegetarians, and 1/2 of 3 are vegetarians. The sum of them is
2/3 of 10 are vegetarians = [tex]\frac{2}{3} \times 10 = \frac{20}{3}[/tex]
1/2 of 3 are vegetarians = [tex]\frac{1}{2} \times 3 = \frac{3}{2}[/tex]
[tex]=\frac{20}{3}+\frac{3}{2}\\\\=\frac{40+9}{6}\\\\=\frac{49}{6}[/tex]
Therefore, 49/6 represents all the sandwiches which are vegetarian.
