Problema Solution
three good friends are in the same algebra class. Their scores on a recent test are three consecutive odd integers whose sum is 219. find each score.
Answer provided by our tutors
let the three consecutive odd integers be:
2x-1, 2x+1, 2x+3, where x is integer
Their scores on a recent test are three consecutive odd integers whose sum is 219:
(2x - 1) + (2x + 1) + (2x + 3) = 219
by solving we find:
x = 36
click here to see the step by step solution of the equation:
2*36 - 1 = 71
2*36 + 1 = 73
2*36 + 3 = 75
the three scores are 71, 73 and 75.
