Question

The sum of three consecutive integers is 90. The least of the three integers is N.

Which equation can be used to find the value of the least integer?

A. (n + 3) = 90
B. n+n+n= 90
C. n+ 2n + 3n = 90
D. n+ (n + 1) + (n + 2) = 90​

Answer 1

Answer: D

Explanation:

Answer 2

D

Explanation:

Since the three integers are consecutive, each is one larger than the last. They can therefore be expressed as n, n+1, and n+2. If you add them all together, you will get 90, so the appropriate equation is n+(n+1)+(n+2)=90, or choice D. Hope this helps!
