So if one bit of the length, is half the size of the other bit then we can make the following equation, for x being the length of rope:
x + 2x = 66
3x = 66
x = 22
That is the length, of the smaller one (half the big one), so 2x = 44. Hence d) is your answer.
Hope I helped!
I'm pretty sure that it's b. That's assuming that you find the negative of b^2 and not the square of negative b.
40 mowers = $4,776
Multiply the above equation by 3
120 mowers = $14,328
5/8 * 2 =
10/8 =
5/4
-------------------
your answer is 5/4
