Answer:
22 rooms
Step-by-step explanation:
If two gallons of paint covers 3 rooms then you need to divide 15 gallons of paint by 2 gallons of paint = 7.5 gallons of paint. then you need to multiply 7.5 gallons of paint by 3 rooms = 22.5..... so that means you can paint 22 full rooms.
Answer:
n = -45
Step-by-step explanation:
(n-5) /10 = -5
Multiply each side by 10
(n-5) /10 *10= -5*10
n-5 = -50
Add 5 to each side
n-5+5 = -50+5
n = -45
To solve a problem like this, we can setup a basic algebraic equation.
52+14=x
66=x
We know this equation is true because 14 years ago, she was 52 so 14 years later, she is 66.
