Answer: 4y
Step-by-step explanation:
Distribute the negative sign to get rid of the parentheses
y+3y = 4y
Assuming that it is a square board, she would not have enough. This is because there would be twice as much height and twice as much width. Those numbers add up to far more.
However, if they just have to cover those two sides they will have 0.45 left. You can get this by subtracting the amounts from the overall.
46.25 - 37.5 - 8.3 = 0.45
I think the answer is 66. But I'm not sure just try and see...!
24 ft 2 1/4 inches - 23 ft 9 1/2 inches = 4 3/4 inches.
4 3/4 inches would tie it, so now add 1/4 more inches:
4 3/4 + 1/4 = 5 inches.
He needs to jump 5 inches more.
