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.
