Water come out of a pipe at a rate of 16 gallons per minute. How many gallons have come out after 4 minutes​

64 gallons

Step-by-step explanation:

Ask yourself; if

 16gallons = 1minute

     ?           = 4minutes

Cross multiply;

(16 × 4) ÷ (1) = 64

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
