Divide total miles driven by number of gallons of gas used.
243 miles / 9 gallons = 27 miles per gallon
324 miles / 12 gallons = 27 miles per gallon.
She can drive 27 miles on one gallon of gas.
Answer:
x = 4 y = 21
Step-by-step explanation:
16x - 23 = 10x + 1
16x - 10x = 23 + 1
6x = 24
24/6 = x
x = 4
16(4) - 23 = 41
41 + (180 - 62) + y = 180
41 + 118 + y = 180
y = 21
x = -75
