Answer:
B) -7m - 8 = m - 4
D) m - 4 = -7m - 8
E) -8 - 7m = -4 + m
Step-by-step explanation:
Solve all of the equations to see if they end up with the same result. Start with the original:
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m (now we know B and D and E are correct)
-7m - m - 8 = -4 + m - m
-8m - 8 = -4
-8m - 8 + 8= -4 + 8
-8m = 4
Answer: 8.5π

If I understand the question correctly, the entire circle has an Area of 9π and you are looking for the Area of the shaded region which has a central angle of 
the section of the circle that is shaded is 
Area of the shaded region is: 
The distributive property:
a(b + c) = ab + ac
2(x - 8) = 68
(2)(x) - (2)(8) = 68
2x - 16 = 68 |+16
2x = 84 |:2
x = 42
Answer: D. 42
If 140 tourists are split up 9 per each of 15 vans, 15×9=135 which is the amount of people able to occupy a van. if there is 140 tourists and only 135 can go on a van you do 140-135=5, that means your remainder is 5.
your remainder represents the amount of people unable to board a van.
Answer:
C - AC equals AD times AB over AE
Step-by-step explanation:
If Hiro is creating a larger scaled replica of a triangular canvas, then Hiro will get two similar triangles ABE (the small one) and ACD (the large one). Similar triangles have proportional corresponding sides, so

From this proportion:

So, option C (AC equals AD times AB over AE) is correct option
