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!
After 3 hours.
working;
after 3 hours, Terry will have completed 15 hours + 10*3 hours=45 tasks
Susan will have completed 9+ 12*3hours= 45 tasks
M + (-9.5) = -7.8
First, simplify your brackets. / Your problem should look like:
Second, change addition to subtraction. / Your problem should look like:
Third, add 9.5 to both sides. / Your problem should look like:
Fourth, simplify. / Your problem should look like:

Answer:
m = 1.7
The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.
I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
