Write the Distributive Property of the following expression using the GCF: 15 + 20 =
A. 1(15 +20)
В. 5 (3+4)

B

Step-by-step explanation:

GCF = greatest common factor

5 is bigger than 1

and 5 can divide both of them so it is the GCF when you expand the brackets you will get 15+20

I hope this makes sense I'm not too good at explaining

martin paints at a unit rate of 1.6 gallons per wall ( that means 1.6 gallons are used to paint 1 wall) or 0.625 wall per gallon (that means 0.625 wall is painted by 1 gallon)

Step-by-step explanation:

5 walls = 8 gallons

1 wall = 8/5 gallons  ( we divided both sides by 5 since we want to know how many gallons would be needed for 1 wall)

1 wall = 1.6 gallons

if we are to calculate gallon per wall, it would be

8 gallons = 5 walls

1 gallon = (5/8) walls

1 gallon paints 0.625 wall

to calculate for 15 walls knowing the rate of gallons per wall

so if 1 wall = 1.6 gallons

then 15 walls = 1.6 * 15 = 24 gallons

similarly, using walls per gallon (this is a longer method)

0.625  walls = 1 gallon

0.625 = 5/8 walls ( so what do we multiply with this figure to give us 15 walls?)

15 / (5/8)

(15 *8)/5 = 3*8 = 24 gallons

so 15 walls would need 24 gallons

clear ? if not please let me know
