Carlos is five years older than twice his sister's age. carlos is 13.
which equation and solution correctly identifies his sister's age?

Answer with Step-by-step explanation:

Let Carlos sister's age be y.

Carlos is 13.

Carlos is five years older than twice his sister's age.

⇒ 13=2y+5

or 2y+5=13

Equation which  correctly identifies his sister's age is:

2y+5=13

⇒ 2y=13-5

⇒ 2y=8

Dividing both sides by 2 gives

y=4

Hence, Carlos sister's age is:

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
