15 gallons is the best because you get 15 gallons for 48.75 and 2gallons for free
exp. 20gal for $70
50quarts= 12.5 gal for $33.50
15 plus 2 gal is 17 for 48.75 much cheaper
mark me as brainlest
2y = 2x + 10
y = x + 5

Answer:
QS = 38
Step-by-step explanation:
First, we need to find the value of x.
Given that R is the midpoint of Q and S, that means QR = RS.
6x-11 = 2x+9
Solve.
x = 5.
To find QS, we need to solve the following equation:
6x-11 + 2x+9
Substitute 5 for x.
6(5)-11+2(5)+9
30-11+10+9
38
