Answer:

Sheri's age = 10

Terry's age = 30

Step-by-step explanation:

Sheri’s age in 20 years time will be the same as Terry’s age is now. Ten years from now.

Let T be the Terry's age

And S be the Sheri's age

S+20= T

Ten years from now, Terry’s age will be twice Sheri’s age

T+10= 2(S+10)

T+10= 2S+20

Subtract 10 from both sides

T= 2S+10

Now we replace T by 2S+10 in the first equation

S+20= T

S+20= 2S+10

Subtract S from both sides

20=S+10

Subtract 10 from both sides

S= 10

T= 2S+10

T= 2(10)+10=30

Sheri's age = 10

Terry's age = 30

I think the answer is C.

First start by factoring, you should get (2n-3)(n-2)=0

Then start to solve for n.

2n-3=0

n-2=0

n=2, n= 3/2

I hope that helps.
