Answer:
Step-by-step explanation:
1.you have to set up a proportion(x/120 = 20%/100%
2.you have to cross multiply
3.you have to divide 100x by the number you get
4.you got your answer.
To solve for y, you need to separate it in one side and the other terms in the other side..... as follows:
<span>a(n+y)=10y+32a
an + ay = 10y + 32a
an - an + ay = 10y + 32a - an
ay = 10y + 32a - an
ay -10y = 32a - an
y (a-10) = (32 - n)a
y = {a(32-n)} / (a-10)

Answer:
-2
Step-by-step explanation:
the slope is -2 because it says -2x and the number attached to x is the slope
Answer:
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Side a = 60 cm
Side b = 80 cm
Side c = 100 cm
The formula of right triangle is as follows,
By putting the value in the formula, we get
= 3,600 + 6,400 = 10,000
= 10,000 = 10,000
As, L.H.S. = R.H.S.
Hence, this shows it is a right triangle.
Graph C is the answer.
2x – y ≥ 3x + 2y < 4
=y is less than or equal to 2x-3
y is less than -x/2+2
