Answer:
Step-by-step explanation:
17x - 5(12x - 2y) = 5(4y + 3 + 2x)
Distribute
17x - 60x + 10y = 20y + 15 + 10x
Combine like terms
-43x + 10y = 20y + 15 + 10x
Subtract 10x to both sides
-43x + 10y - 10x = 20y + 15
-53x + 10y = 20y + 15
Subtract 10y to both sides
-53x = 20y + 15 - 10y
-53x = 10y + 15
Divide both sides by -53

Answer:
9.25≤x≤64.15
Step-by-step explanation:
The smallest amount would be 5 of the least priced item
5 * 1.85 =9.25
The largest amount would be 5 of the greatest priced item
5 * 12.83 =64.15
9.25≤x≤64.15
Let us set up some variables:
Now let us set up some equations based on the facts:
- length of rectangle is 4 times its width --> L = 4W
- perimeter of rectangle is 80 --> 2L + 2W = 80
Equations:
L = 4W -- equation 1
2L + 2W = 80 -- equation 2
Plug the value of L from equation 1 into equation 2
2(4W) + 2W = 80
8W + 2W = 80
10W = 80
W = 8 -- equation 3
Plug the value of W from equation 3 into equation 1:
L = 4W = 4 * 8 = 32
Therefore the length is 32 and the width is 8.

Answer: #1
Explanation:
Because the y int represents the starting point which in this case is -7 and the slope is -3/1 which represents the direction that the fish is swimming in (up or down)
