Answer:
x = 136°
Step-by-step explanation:
We can use a theorem to help us.
<em>Theorem: </em>
<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.</em>
For exterior angle x, the remote interior angles are z and <CBD.
From the theorem, we get this equation.
x = z + m<CBD
We know z = 52°.
We need to find m<CBD.
Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.
m<CBD + y = 180°
m<CBD + 96° = 180°
m<CBD = 84°
x = z + m<CBD
x = 52° + 84°
x = 136°
<u>Answer: </u>
clerk A and clerk B can simultaneously stock a shelf in 
minutes
<u>Explanation:</u>
Let the first clerk be A and the second clerk be B
A can stock a shelf in 20 min
B can stock a shelf in 45 min
Consider the complete work to be W
A’s rate of stocking = 
per minute
B’s rate of stocking = 
per minute
When, A and B work simultaneously, rate of work done = 
Total work done simulatenously = 
=
Therefore, clerk A and clerk B can simultaneously stock a shelf in minutes
5. the first equation gives you the value of y. So plug in the value of y into the second equation:
3x+2(-x-7)=3.
Simplify: 3x-2x-14=3.
Subtract: 1x-14=3.
Add 14 to both sides: x=17.
Now you know the x value.
You plug in the x value into the first equation: y=-17-7
Solve: y=-24
Answer: 17, -24
The answer is 2
One Solution
6s-10= 1s
-6s -6s
_________
-10=-5s
Divide -10 and -5
You'll get 2
X=1
based on the options given, it looks like -2x+5y would be correct although i am not certain
