Hi there! To help you with this, all you have to do is add or subtract the number on the left, depending what the number is to get the variable by itself. If the number is positive with a plus sign, you add. If the number is negative with a minus symbol, you add. With that being said, here are the answers to help you out.

1. B: 8
2. A: 8
3. A: 25
4. C: -1

1/x + 1/4 = 7/12 solve for x
Licemer1 [7]
Given equation is
\frac{1}{x} +  \frac{1}{4} =  \frac{7}{12}

We can solve it by subtracting 1/4 both side
\frac{1}{x} +  \frac{1}{4} -  \frac{1}{4} =  \frac{7}{12} -  \frac{1}{4}

\frac{1}{x} =  \frac{7}{12} -  \frac{1}{4}
                          =  \frac{7 - 3}{12}
                          =  \frac{4}{12}
                          =  \frac{1}{3}

So \frac{1}{x} =  \frac{1}{3}
On comparing x = 3.

SO the solution of equation is x = 3

Find BC. Round to the nearest tenth
SSSSS [86.1K]
<span>Using LAW OF SINES Round to the nearest tenth. 
Find BC: triangle is laying on it's side with the point to the right point(A).

B to C= 61 degrees
C to A= 23 cm
A to B= 12 degrees
--------------------
If I interpret this correctly:
Angle A = 61º

Angle C = 12º
--> B = 103º
-------------
Side b = 23 cm
--------------
BC is side a, opposite angle A
--------------
23/sin(103) = a/sin(61)
a = 23*sin(61)/sin(103)
a =~ 20.6 cm 

Hope this helped :)</span>

Given these angles: m∠3 = 82°, m∠4 = 98°.
RSB [31]
These angles are supplementary.
Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees. 82 degrees + 98 degrees = 180 degrees.
