Answer: 9
Step-by-step explanation: just devide then times
First factor the equation
(x-10)(x+2) = 0
Then solve for (x-10) and (x+2)
x=10
x=-2
Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
The constant of proportionality should be 45 miles per hour, and the car should travel 135 miles in three hours.
