The side length of Rs is dependent on QRS
His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.
He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal
He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal
With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles
9. Let p = Pico
3/4p = 18
10. Let h = height with pedestal and foundation
151 + h = 305
11. Let m = Meredith
19 = 3 + 2m
12. Let p = number of pizzas, $5 off is - 5 from regular price
3p - 5 = 21.75
13. Option C.
14. Option A.
15. Let w = last week's miles
w =

(12) + 3
The word "half" tells you to use 1/2 in the equation. The phrase "three more than" tells you to use + 3. We multiply 1/2 by 12 (or divide 12 by 2; it's the same thing) because we are taking half of the miles Carmen ran "this week" as stated in the problem.
