Answer:
The number of cars must they wash in order to have enough money to pay for the trip is 40.
Step-by-step explanation:
The total amount of money required for the four student government officers to go to the state convention is:
The amount saved for the convention in the student government savings account is $495.
The additional amount required is:
Additional amount = Amount Required - Amount Saved
= $655 - $495
= $160
The four students decided to earn the additional amount by washing cars.
They charge $4 for each car wash.
Compute the number of car wash the students must do is:
Thus, the number of cars must they wash in order to have enough money to pay for the trip is 40.

Count every number less than 70 (count the leaf plot numbers if that helps).
62,62,63,64,54,56,56 = 7 drivers that travel less than 70 mph
Answer: The value of x is 8
Step-by-step explanation:
3(x + 5) − 3 = 52 − 2x
First open the bracket, and do multiplication
3x + 15 - 3 = 52 - 2x
3x + 12 = 52 -2x
Collect like terms, and make the whole expression equal to zero
3x + 12 - (52 - 2x) = 0
3x + 12 - 52 + 2x = 0
3x + 2x + 12 - 52 = 0
5x - 40 = 0
5x = 40
Divide both sides by 5
5x/5 = 40/5
x = 40/5
x = 8
