Answer:
x = 27
Step-by-step explanation:
ΔBRD and ΔQCD are similar, hence the ratios of corresponding sides are equal, that is
= 
note that BD = 26 + 39 = 65
substitute values into the ratio equation
= 
( cross- multiply )
65x = 39(x + 18)
65x = 39x + 702 ( subtract 39x from both sides )
26x = 702 ( divide both sides by 26 )
x = 27
Answer:
63%
Step-by-step explanation:
37% did not solve problem 2
100% - 37% = 63%
Answer: 
Step-by-step explanation:
If we have y=7x-1/2, the inverse is where we solve for x instead of y.
We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.
Therefore, .

There are 12 months in a year, and 15 years to pay the mortgage.
Therefore you are simply doing 12 multiplied by 15.
12 × 15
= 180
So your answer is C. 180
Answer:
length = 20m
width = 16m
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
Firstly, I would assume that you made a unit error for the perimeter, which I would believe is meters.
With that, we can now make these statements:
Perimeter = 72m
Perimeter = 2l + 2w
therefore,
2l + 2w = 72
Since the question states the width is 4 meters less than the length, we can make this statement,
w = l - 4
We can now substitute this into the first statement we made, 2l + 2w = 72
2l + 2(l - 4) = 72
2l + 2l - 8 = 72
4l - 8 = 72
4l = 80
l = 20m
Using the second statement, w = l - 4, we can now find w,
w = 20 - 4
w = 16m
Therefore, the length is 20m and the width is 16m
