Answer:
Therefore the required equation is C = $ 15p - 60
Step-by-step explanation:
i) the price per gallon of paint = $p
ii) promotion offering price per gallon = $(p-4)
iii) cost of 15 gallons at the rate of promotion offering, C = 15(p - 4) = 15p - 60
Therefore the required equation is C = $ 15p - 60
Answer: at 50 mph, she drove for 4 hours.
at 45 mph, she drove for 2 hours.
Step-by-step explanation:
Let t represent the time that she spent driving at 50 miles per hour.
Taylor took 6 hours to drive home from college for Thanksgiving break. This means that the time that she spent driving at 45 miles per hour is (6 - t) hours.
Distance = speed × time
Distance covered while driving 50 miles per hour is
50t
Distance covered while driving 45 miles per hour is
45(6 - t)
Since the total distance that she drove is 290 miles, it means that
50t + 45(6 - t) = 290
50t + 270 - 45t = 290
50t - 45t = 290 - 270
5t = 20
t = 20/5 = 4
At 45 miles per hour, she drove at
6 - 4 = 2 hours
Answer:
3.2
Step-by-step explanation:
Answer:
m = -3
Step-by-step explanation:
−m − 19 = 8m + 8 (Simplify equation)
−9m − 19 = 8 (Subtract 8m from both sides)
−9m = 27 (Add 19 to both sides)
m = -3 (Divide both sides by -9)
Your answer would be, -6ap^3
