I think the constant variation is -2 (8÷-4)
Answer:
585.57
Step-by-step explanation:
Maya got 286.00
if lian got 192.84 less than we do 286-192.84 which is 93.16
if lian got 93.16, we add 113.25 to 93.16 to get rei's amount.
113.25 + 93.16 = 206.41
Now we add all their amounts, 286+93.16+206.41
585.57
Answer:
y = 12
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
15 - 4y = - 21 - y
15 + - 4y = - 21 + - y
- 4y + 15 = - y - 21
Step 2: Add y to both sides.
- 4y + 15 + y = - y - 21 + y
- 3y + 15 = - 21
Step 3: Subtract 15 from both sides.
- 3y + 15 - 15 = - 21 - 15
- 3y = - 36
Step 4: Divide both sides by - 3.
- 3y/- 3 = -36/- 3
y = 12
I am so sorry if it is long and confusing, but, I hope this still helps!
[7, 2] + ([-3, 6] - [2, -4]) = [2, 12]
