Three good friends are in the same algebra class. Their scores on a recent test are three consecutive even integers whose sum is
klio [65]

Let the lowest score be x.

<u>The 3 consecutive even scores are:</u>

1st score = x

2nd score = x + 2

3rd score = x + 4

-

<u>Sum of their score is 270:</u>

x + (x + 2) + (x + 4) = 270

-

<u>Solve x:</u>

x + (x + 2) + (x + 4) = 270

x + x + 2 + x + 4 = 270

3x + 6 = 270

3x = 264

x = 88

-

<u>Find their scores:</u>

1st score = x = 88

2nd score = x + 2 = 88 + 2 = 90

3rd score = x + 4 = 88 + 4 = 92

-

Answer: The scores are 88, 90 and 92
