Step-by-step explanation:
4x + 12° = 64° ( vertically opposite angle )
4x = 64° - 12°
4x = 52°
x = 52° / 4
x = 13°
hence the value of x is 13°
<em>subtract 2 from both sides</em>
<em>divide both sides by (-4)</em>

If you would like to know how many people attended the reunion last year, you can calculate this using the following steps:
125% of last year's attendance is 160 people
125% of x is 160
125% * x = 160
125/100 * x = 160 /*100/125
x = 160 * 100 / 125
x = 128 people (last year)
Result: 128 people attended the reunion last year.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
Answer:$21.207 or $21.21
Step-by-step explanation:
You would take $24.95 *85% (that is how much you are going to pay) and the result is your answer
