Suppose y is inversely proportional to x. If y = –8 when x = –2, find y when x = 32
Annette [7]

Answer: 1/2

Explanation:

When y is inversely proportional to x. This implies that:

y = k/x

If y = –8 when x = –2, then the constant of proportionality will be;

y = k/x

-8 = k/-2

k = (-8 × -2)

k = 16

when x = 32, the value of y will be:

y = k/x

y = 16/32

y = 1/2

The five members of the traynor family each buy train tickets. During the train ride, each family member buys a boxed lunch for
OLga [1]

Answer:

Each ticket is $43.20

Explanation:

If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.

$6.50 × 5= $32.5

Now we subtract the meals from the total of $248.50.

$248.50 - $32.5= $216

All five tickets cost $216, now we divide this by 5 since five tickets were bought.

\frac{216}{5}= $43. 2

Each ticket was $43.20

Let's double-check:

$32.5 + $43.20(5)= $32.5 + $216= $248.50
