Alex weighs 85 pounds. Together, he and his sister weigh ten pounds more than five times the weight of his sister. What is the weight, w, of Alex's sister?

Question

A) 85 + w=5w - 10
B) 85 + w - 10=5w
C) 85 + w=5w
D) 85 + w=5w + 10

Answer 1

To solve this, we can first set up an equation. Let w be the weight of Alex's sister.

Given that Alex weighs 85 pounds, the total weight of Alex and his sister is 85 + w. And we know that the total weight is ten pounds more than five times that of his sister.

Therefore, we can write the equation as:

85 + w = 5w + 10

Solving this equation will give us the weight of Alex's sister.

C) 85 + w = 5w
