R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
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
I think it is asking for the answer, therefore it would be AB = 10.7
I think all you have to do is add all the digits
Answer:
Each is 16 because 8 x 8 = 64 divided by 4 = 16
