First let's get rid of the parenthesis:
12 - 4x + 3x = 4 + 10 + 2x
Now group the x's on the left and the numbers on the right
-4x + 3x - 2x = 4 + 10 - 12
...and simplify
-3x = 2
divide by -3 to isolate x
x = -2/3

Step-by-step explanation:
A. P(top)=top outcomes/all kinds of outcomes=4/30=2/15=13.33333333333...%
P(bottom)=bottom outcomes/ all kinds of outcomes=1/30=3.33333333....%
P(side)=25/30=5/6=83.33333333333...%
B. No. If were equally likely, the probabilities for A would have been roughly the same. It seems like the side event is more probable.
Answer:
Step-by-step explanation:
We are asked to divide our given fraction: 
.
We will simplify our division problem using rules of exponents.
Using product rule of exponents 
we can write:
Substituting these values in our division problem we will get,
Using power rule of exponents 
we will get,
Using quotient rule of exponent 
we will get,
Using product rule of exponents we will get,
Upon canceling out 
we will get,
Using power rule of exponents we will get,
Therefore, our resulting quotient will be .
Angle B corresponds to angle D, therefore they are equal. To find Angle B's length, add the two known angle measures then subtract the sum from 180. (All angle measures in a triangle equal 180 when added)
32 + 41 = 73
180 - 73 = 107
<h3>Answer:</h3>
<u>Angle B = </u><u>107º </u>
hope this helps :)
The answer is 16%. 4/25=0.16
