C

x = 50

If the two angles add up to 140 then that means 40° + 2x° equals 140

Set up an equation from that evaluation and solve

40 + 2x = 140

Subtract 40 from both sides

2x = 100

Divide both sides by two

x = 50

Hope this helps.

step-by-step explanation:

2 x 40 = 80

80/5

= 16

part a

5     5.5  

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
