Question

Which equation models the following word problem?Find three consecutive odd integers such that the sum of 3 times thesmaller and 5 times the largest is 770.

Answer 1

AExplanations:

• Some examples of odd numbers are 1, 3, 5, 7, 9, and 11, we cand see that this is an addition of 2 to the previous number.

So,

• Let x be the smaller inter ... ................(1)

• let x + 2 = the middle interger.......... (2)

therefore the third odd interger will be

• (x+2) +2 = (x+4) ........................................(3)

Solving this according to the given statement will be :

• the sum of 3 times the smaller = 3x

,

• 5 times the largest = 5*(x+4)

combining this would be : 3x + 5(x+4) = 770

Option D is correct .
