Every minute, 2 gallons of water flows from a shower. A family of 5 people showers for an average of 9 minutes per person every morning. How many gallons of water does the family use for showering every morning?

90 gallons

Step-by-step explanation:

5 people at 9 minutes each = 45 minutes

2 gallons per minutes * 45 minutes

90 gallons

90 Gallons

Step-by-step explanation:

So to start we know that

a. every 1 min = 2 gallons

b. 5 ppl shower for 9 minutes each (on average)

so we can solve we multiplying amt. of ppl showering and the mins. they shower which is 5 and 9 respectively => and we get 45 minutes taken.

We know that each minute equals 2 gallons so we simply multiply 45 and 2 = 90 => and thus, we have our answer of 90 gallons.

Hope this helps!

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
