11. One One Cup of popcorn kernels are popped. They create five bowls of popcorn. How many bowls of popcorn would there be if eight cups of kernel were popped?

Answer 1

If one cup of popcorn kernels creates 5 bowls of popcorn, then 8 cups of popcorn kernels would create 8*5 = <<8*5=40>>40 bowls of popcorn. Answer: \boxed{40}.

Answer 2

12. Rebecca bought a video game in Miami. They came was $30. Miami has a 7% sales tax. How much money did Rebecca pay for the video game including sales tax?

Answer 3

The sales tax on the video game would be 7/100 * $30 = $<<7/100*30=2.1>>2.1.
Therefore, Rebecca paid a total of $30 + $2.1 = $<<30+2.1=32.1>>32.1 for the video game including sales tax. Answer: \boxed{32.1}.

Answer 4

13. Simplyfy the expression

(7x+6) - (8+x)9

Answer 5

Let's simplify the expression step by step:

(7x+6) - (8+x)9

First, distribute the 9 to the terms inside the second parentheses:
(7x+6) - (72+9x)

Next, distribute the negative sign to each term inside the second parentheses:
7x+6 - 72 - 9x

Combine like terms:
(7x - 9x) + (6 - 72)

Simplify:
-2x - 66

Therefore, the simplified expression is \boxed{-2x - 66}.

Answer 6

13. Simplyfy the expression

(7x+6) - (8+x)

Answer 7

Let's simplify the expression step by step:

(7x+6) - (8+x)

First, distribute the negative sign to each term inside the second parentheses:
7x+6 - 8 - x

Combine like terms:
(7x - x) + (6 - 8)

Simplify:
6x - 2

Therefore, the simplified expression is \boxed{6x - 2}.

Answer 8

14. Jill is thinking of a number four more than three times the number is 13 what is the number jill is thinking of?

Answer 9

Let's solve this problem algebraically.

Let's call the number Jill is thinking of "x".

We're told that four more than three times the number is 13. Translating this into an equation, we get:
3x + 4 = 13

To isolate the variable x, we subtract 4 from both sides of the equation:
3x = 13 - 4
3x = 9

Finally, divide both sides by 3 to solve for x:
x = 9/3
x = 3

Therefore, the number Jill is thinking of is 3.

15. To let her car, you need to pay a flat fee Plus $0.20 for each mile that you drive. Which equation would be used to solve for the price of the initial fee if the total cost of a rental was $60 when the car was driven 40 miles?

Answer 11

Let's call the initial fee "F" (in dollars) and the number of miles driven "M".

According to the information given, the total cost of a rental is $60 when the car was driven 40 miles.

To find the equation that relates the initial fee and the total cost, we can use the equation:

Total Cost = Initial Fee + (Cost per Mile) * Number of Miles

In this case, the cost per mile is $0.20.

Plugging in the given values, the equation becomes:

$60 = F + ($0.20) * 40

Simplifying, we have:

$60 = F + $8

To solve for the initial fee "F," we need to isolate it on one side of the equation. Subtracting $8 from both sides gives us:

F = $60 - $8
F = $52

Therefore, the equation used to solve for the price of the initial fee is F = $52.
