Question

Nayeli is the youngest of four siblings whose ages are consecutive even integers. If the sum of their ages is 60, find Nayel

Answer 1

Nayeli is 12 years old

Explanation:

Nayeli is the youngest of four siblings whose ages are consecutive even integers. If the sum of their ages is 60, find Nayel:

Nayel: n

child 2: n + 2

child 3: n + 4

child 4 n + 6

all children = 60 so:

n + n + 2 + n + 4 + n + 6 = 60

combine left side:

4n + 12 = 60

subtract 12 from both sides:

4n + 12 - 12 = 60 - 12

4n = 48

divide both sides by 4:

4n/4 = 48/4

n = 12

so Nayeli is 12 years old
