Problema Solution
Three friends are in the same Algebra class. Their scores on a test are three consecutive even integers whose sum is 270. Find each score.
Answer provided by our tutors
the three consecutive even integers (the scores of the tests) can be written as:
2x - 2, 2x, 2x + 2, where x is integer
their scores on a test are three consecutive even integers whose sum is 270:
2x - 2 + 2x + 2x + 2 = 270
by solving we find:
x = 45
click here to see the step by step solution of the equation:
2*45 - 2 = 88
2*45 = 90
2*45 + 2 = 92
the scores are 88, 90 and 92.
