First you would solve both of the equations, then you would use the subsitution method

Answer: 29</h3>
====================================================
Work Shown:
The two angles shown are a linear pair. They are adjacent and supplementary. Supplementary angles add to 180 degrees.
(4x-5)+(x+40) = 180
5x+35 = 180
5x = 180-35
5x = 145
x = 145/5
x = 29
--------
As a check, if x = 29, then
4x-5 = 4*29-5 = 116-5 = 111
x+40 = 29+40 = 69
The two angles are 69 and 111 degrees which add to 69+111 = 180, which helps confirm the answer.
Answer:
x = 11
Step-by-step explanation:
In ΔSTU ,
m∠S = (11x+3)° ; m∠T = (2x+16)° ; m∠U = (x+7)°
According to angle sum property of a triangle , sum of all the interior angles of the triangle is 180°.
So,




Answer:
x amount of money determines y number of hours to make a painting of that cost.
Step-by-step explanation:
The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).
(x,y)--->(y,x) in the new function.
If the function determines the amount (y) he makes in x hours. The inverse determines how many y hours it takes to earn x amount of money.
Answer: -2.2
Step-by-step explanation:
-10 is the most possible that can be divided by 5, resulting in -2.
The leftover 1 is divided by 5, resulting in .2.
The decimal ends up being -2.2.
