Answer: 42 - 8x

Step-by-step explanation:

Here is the complete question:

Jessica had $15. She bought 3 apples for x dollars each. Levi had $27 and bought 5 apples for x dollars each. Which expression represents how much money both Jessica and Levi have left altogether?

Select one:

27 – 5x

42 – 8x

12 – 2x

39 – 3x

From the question, Jessica had $15. She bought 3 apples for x dollars each. This means she had:

15 - (3 × x) = 15 - 3x

Levi had $27 and bought 5 apples for x dollars each. Levi will have:

27 - (5 × x) = 27 - 5x

The amount they'll have altogether will be the addition of their amount left. This will be:

15 - 3x + 27 - 5x

= 15 + 27 - 3x - 5x

= 42 - 8x

Y is inversely proportional to x, when Y = 2, x = 4.<br><br>Find the value of x when Y = 4.
ratelena [41]

The value of x when y =4 is 2

<h3>How to solve for x?</h3>

An inverse proportion is represented as:

k = yx

Where

k represents the constant of proportion

When y = 2, x = 4.

So, we have:

k =2 * 4

k = 8

Substitute k = 8 in k = yx

So, we have:

yx = 8

When y = 4, we have:

4x = 8

Divide by 4

x = 2

Hence, the value of x when y =4 is 2
