Answer:
65 is the answer.. I used a average calculator https://www.omnicalculator.com/math/average
I think the question is wrong!
It must be
x-4
___= 5
x+2
Answer: x - 4= 5x + 10
or,-10 -4 = 5x - x
or, -14=4x
or,-14/4= x
Therefore, x = -14/4
D) 1.2
Add up all the numbers then divide by how many numbers there are
1. 7 gallons of shampoo will last 5 weeks and 1/4 of another week.
2. 16 Gallons of shampoo will last 12 weeks.
Work Shown
----------------------
0.75 (How much per gallon) × 7 (Gallon of shampoo) = 5.25 (Weeks
0.75 × 16 (How much gallons for 12 weeks) = 12 (Weeks.)
