Question 2

The ages of three friends are consecutively one year apart. Together, their ages total 48 years. Which equation can be used to find the age of each friend (where "a" represents the age of the youngest friend)?

Accepted Answer

a + (a + 1) + (a + 2) = 48

Answer

3a = 48

Answer

a + (a - 1) + (a - 2) = 48

Answer

a(a + 1)(a + 2) = 48

Question 7

Jack bought "j" pairs of jeans at $24.99 each and "s" shirts at $14.99 each, for a total of $104.95 before taxes. Which equation best represents this situation?

Accepted Answer

24.99j + 14.99s = 104.95
