The length of the ramp is unknown.
If 6 ramps were cut from a board that is 12 1/2 feet long, the ramps would be about 2 feet long each which seems like a reasonable answer. The questions regarding how many boards are cut would need the length of the ramps. Lets say that the length is x. You can get 12 1/2 divided by x boards. In order to find out how much is left over, take the number of boards made, multiply it by how long they are. This product is then subracted from 12 1/2.
Answer:
True, True, False
Step-by-step explanation:
4/5, because to simplify a decimal, you can divide the numerator by the denominator. 4 divided by 5 is 0.8
12y = -18x -4x
12y = -22 x
x int = (12,0) when y is zero
y int = (0, -22) when x is zero
