Michael is 3 times as old as Brandon. 18 years ago, Michael was 9 times as old as Brandon.
Mrrafil [7]

Answer: Brandon is 24, Michael is 72.

Step-by-step explanation:

Let m represent Michael

Let b represent Brandon

Then,

m = 3b                    <-----------"Michael is 3 times as old as Brandon."  

m - 18 = 9(b - 18)    <-----------"18 years ago, Michael was 9 times as old as Brandon."  

3b - 18 = 9b - 162

-18 = 6b - 162

144 = 6b

Michael is 3 times as old as Brandon. Also, 18 years ago, Brandon would have been 6 and Michael would have been 54 meaning Michael was 9 times as old as Brandon 18 years ago.

30% = 0.3

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Solution:

To write percent to decimal, divide the number by 100.

$30\%=\frac{30}{100}

       $=\frac{30\div10}{100\div 10}

       $=\frac{3}{10}

       = 0.3

30% = 0.3

Average use of water each day = 90 gallons

30\%  \ \text{of} \ 90=0.3 \times 90

                = 27

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
