Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides
Answer:
I think the answer is 8 blue tiles and 20 green
Step-by-step explanation:
To keep the porportion multiply 2 blue tiles *4
then you need to take 5 green tiles *4
You get 8 blue tiles and 20 Green tiles, and added together you get 28 tiles
y=3 and x= 5
Step-by-step explanation:
- 3×+×=-1 and 4y-2y=3
- 4×=1 and 2y=3
- ×=4-1 and y=3+2
- x=3 and y=5
Rearrange the equation so that x = 11 divided by 1/8
Solve for x (11 divided by 1/8 = 88)
