Answer:
x =42.5
x+8 =50.5
3x+2 = 129.5
Step-by-step explanation:
The two angles shown are supplementary, so they add to 180
x+8 + 3x+2 = 180
Combine like terms
4x+10 = 180
Subtract 10
4x = 170
Divide by 4
x =42.5
x+8 = 42.5+8 = 50.5
3x+2 = 3*42.5 +2 = 127.5 +2 = 129.5
Answer:

For this case, the first thing we must do is define a variable:
g: number of gallons of gas.
c (g): total cost.
We then have a linear function of the form:
c (g) = 2.19 * g
Answer:
A function notation to describe the relationship between the total cost c (g) and the number of gallons purchased is:
c (g) = 2.19 * g
