Yes they are equivalent. You get -3 when you try solving the actual equation.
Is there not more to this problem? maybe thats the final answers
Answer:
1020 raisins
Step-by-step explanation:
The problem tells you the number of raisins is proportional to the number of bags, so there will be "r" raisins in 12 bags:
r/12 = 680/8 = raisins/bag
r = (12/8)(680) = 1020
There will be 1020 raisins in 12 bags.
Answer:
yolo
Step-by-step explanation:
Answer:
x = 2, y= 3
Step-by-step explanation:
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5x-7
y = 5*2 -7
y = 10-7
y =3
