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
Answer:
The diameter of pool a is 10.37 (34 × 0.305)

The circumference of pool B is greater
The area of pool B is 65.7221183130984ft
The area of pool a is
32.5783158177261ft
65.7221183130984 - 32.5783158177261=
Pool Bs area is 33.143802ft² bigger
