Answer:
x=2
Step-by-step explanation:
first divide by 3 left and right, then you get:
x+1 = 3
then subtract 1 left and right, then you get:
x=2
so, solutions appear by simplifying
437/19=23

Answer:
A reflection over line y=x.
Step-by-step explanation:
Answer:
Step-by-step explanation:
We want to find the distance of <em>d</em> or AB.
From the right triangle with a 35° angle, we know that:
And from the right triangle with a 42° angle, we know that:
AB is PA subtracted from PB. Thus:
From the first two equations, solve for PB and PA:
And:
Therefore:
Using a calculator:
The answer is:
B) The solution is (4, 200). This means that it will cost me $200 to go to either gym 4 times.
the equations given to you were:
(C = 100 + 25x) and (C = 50x)
well, if you plug in 200 for C and 4 for x you get these equations,
200 = 100 + 25(4), and 200 = 50(x)
I solved both step-by-step below.
1. C = 100 + 25x plug in points
200 = 100 + 25(4) solve the parenthesis's
200 = 100 + 100 combine like terms
200 = 200 both sides are equal
2. C = 50x plug in points
200 = 50(4) solve the parenthesis's
200 = 200 both sides are equal
