Question 13Find three consecutive even integers such that the sum of twicethe smallest and three times the largest is 42.Question 14 Anthony has a total of $4.20 in nickels, dimes and quarters. If hehas 6 more dimes than nickels and three times as many quartersas nickels, how many of each kind of coin does he have?

Answer 1

Given data:

Let the three consecutive even inetgres are a-2, a, a+2.

the sum of the twice the smallest and three times the largest is 42.

2(a-2)+3(a+2)=42

2a-4+3a+6=42

5a+2=42

5a=40

a=8

Thus, the even integrers are 6, 8, 10
