Question 104224: Angela's average for six math tests is 86. On her first tests she had scores of 80, 88, 82, 93. On her last test, she scored 7 points lower than she did on her fifth test. What scores did Angela receive on her fifth and sixth tests? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Let x = Angela's score on the 5th test, then (x-7) is her score on the 6th test.
To find the average score, you add the six scores and divide by 6. Add the numbers in the numerator and then multiply both sides by 6. Subtract 336 from both sides. Divide both sides by 2. This is Angela's score on the 5th test. This is Angela's score on the 6th test.
