Y=-x+1<br> -2x-y=2 substitution
UNO [17]

Step-by-step explanation:

y=-x+1 \\ -2x-y=2given

- 2x-( - x + 1)=2  \\  - 2x + x - 1 = 2 \\  - x = 2 + 1 \\  - x = 3 \\ x = 3

put x

-2( - 3)-y=2  \\ 6 - y = 2 \\  - y = 2 - 6 \\  - y =  - 4 \\ y = 4

Help please <br> 75<br> 77<br> 82<br> Show your work
Daniel [21]

Answer:Jarvis's class average is 75

Step-by-step explanation:

The total possible average score for the math course is 100

a) If the teacher rates homework at 10%, it means that the total possible score for homework

is 10/100 × 100 = 10

If his homework average is 93, then his score would be

(93×10)/100 = 9.3

b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes

is 30/100 × 100 = 30

If his quiz average is 82, then his score would be

(82×30)/100 = 24.6

c) If the teacher rates test at 40%, it means that the total possible score for quizzes

is 40/100 × 100 = 40

If his quiz average is 72, then his score would be

(72×40)/100 = 28.8

d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes

is 20/100 × 100 = 20

If his final exam is 60, then his score would be

(60×20)/100 = 12

Jarvis's class average would be

9.3 + 24.6 + 28.8 + 12 = 74.7

Approximately 75
