Answer:

She pays $240 for 8 lessons.

Step-by-step explanation:

We need to set up equivalent ratios so we can cross-multiply and solve for x, the amount Angela pays for 8 lessons. Make sure to have both the costs in the numerator, and the number of lessons in the denominator. If you mix it up, this won't work.

\frac{120}{4} = \frac{x}{8}

Cross-multiply:

120*8 = 4x

Solve for x:

960 = 4x

960/4 = x

<u>x = $240</u>

Ben spent 1/6 of his money on a burger, fries, and a drink. Then he spent half of the money he had left: $5 on a magazine, $8.25
Ket [755]

The amount of money Ben had to begin with after spending 1/6 and 1/2 of it is 57 dollars.

<h3>How to find the how much money he had with an equation?</h3>

let

x = amount he had to begin with

He  spent 1/6 of his money on a burger, fries, and a drink. Therefore,

amount spent on burger, fries, and a drink = 1  / 6 x

Hence,

amount he had left = x - 1 / 6 x =6x - x /6 = 5 / 6 x

Then he spent half of the money he had left.

1  / 2(5  /6 x) = 5 + 8.25 + 10.50

5 / 12 x = 23.75

cross multiply

5x = 23.75 × 12

5x = 285

divide both sides by 5

x = 285 / 5

x = 57

Therefore, the amount of money he have to begin with is $57.

PLEASE HELP MEEEE THANKS IF YIU DO
castortr0y [4]

B. Not moving, is the correct answer.

A is not correct because constant speed on a distance vs. time graph would vertically point to the right. C is not correct because acceleration on a distance vs. time graph would curve upwards. D is not correct because B applies to the graph.

Hope this helps :)
