Answer:
83.15
Step-by-step explanation:
Joey's current grade can be determined by weighting his scores with the weights given and adding the results
Tests = 0.6 x 82 = 49.2
Quizzes = 0.25 x 77 = 19.25
homework = 0.15 x 98 = 14.7
49.2 + 19.25 + 14.7 = 83.15
Answer: x = 2.4 or 12/5, y = -1.2
Step-by-step explanation:
-2x + y = -6
=> y = 2x - 6
-x + 3y = -6
=> -x + 3(2x - 6) = -6
=> -x + 6x - 18 = -6
=> 5x = 12
=> x = 12/5 or 2.4
-x + 3y = -6
=> - (2.4) + 3y = -6
=> 3y = -6 + 2.4
=> 3y = -3.6
=> y = - 1.2
