So, 2x8=16 which 2(8x) =16x -> 2x7=14 which 2(7) = 14 now, 16x+14 23+5=28, 28(x-4) is 28x-112 ?? I don’t know if you have an idea of what I just said lol ( I’m not sure about 112, sorry ) I don’t know if that helps
Question is there a Picture with the question? Cause that would help me figure out the question.
Answer:
D would be the best answer. Because 2 x 8 = 16
Step-by-step explanation:

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.
sin

.7

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.
θ
=
arcsin
(
1
6
)
θ
≈
10
∘
which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around
170
∘
, but we can rule that out as a value for a ramp wedge angle.
M = 4b
m = b + 27
4b = b + 27
4b - b = 27
3b = 27
b = 27/3
b = 9......Brandon is 9
m = 4b
m = 4(9)
m = 36.....Michael is 36
