Roy is twice as old as Joan, and in 3 years the sum of their ages will be 21 years. Find their present ages.

Lisa [10]

Answer:

Roy is 10 years old at present and Joan is 5 years old at present

Step-by-step explanation:

Let

x----> Roy's age

y----> Joan's age

we know that

x=2y ----> equation A

(x+3)+(y+3)=21 ----> equation B

substitute equation A in equation B

(2y+3)+(y+3)=21

solve for y

3y+6=21

3y=21-6

3y=15

y=5 years

Find the value of x

x=2y ----> x=2(5)=10 years

therefore

Roy is 10 years old at present

Joan is 5 years old at present

lisov135 [29]

$1 \% = \frac{1}{100}\\ \\90 \% * x =6.4 \\ \\\frac{90}{100}x=6.4 \\ \\\frac{9 }{10 }x=6.4 \ \ *(\frac{10}{9})\\ \\x= 6.4 *\frac{10}{9}\\ \\x=\frac{64}{9}\\ \\x = 7\frac{1}{9}$
