I NEED HELP ASAP PLEASEEEEEE
Matthew is 7 years older than twice the age of his sister. If Matthew is 13, how old is his sister?
A:3
B:4
D:10
C:33

Respuesta :

Mibo

Step-by-step explanation:

The answer is 33 because

If Mathew is 13 then twice is 13 x 2 = 26

Then 7 years older so 26 + 7 = 33

Answer:

I think the answer is A.

Step-by-step explanation:

I would write the equation using x as Mathew's sisters age so his sister's age is 2x + 7 = 13 and then solve for x. Subtract 7 from both sides which leaves

2x = 6, divide both sides by 2 which is 3. Hope that helps.
