Answer:
x = 69 degrees
Step-by-step explanation:
180 - 146 = 34
180 - 77 - 34 = 69
x = 69 degrees
Ok so first off understand what they are saying. there is a movie on sale for $22.10 which is 15 percent of the original price. So now what you do is set up the problem.
22.10 is = 15% of the price
x = 100% of the price (original price)
<u> 15 </u> = <u>22.10
</u>100 x
<u>
</u>now just use cross multiplication.
15x = 22.10 · 100
solve for x.
<u>15x</u> = <u>2210</u>
<u /> 15 15
x = 147.33333333 since the 3's go on forever you can simply put it into a fraction
x = 147 <u>3
</u> 9
<u>
</u>whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9

Step-by-step explanation:
<u>Step 1: Define</u>
5x - 6 = 4x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
- Isolate <em>x</em> terms: x - 6 = -12
- Isolate <em>x</em>: x = -6
