It looks like you gotta to PEMDAS
20) m∠6 = m∠7 because they are vertical angles.
7x - 24 = 5x + 14
7x = 5x + 38
- Subtract 5x from both sides.
2x = 38
x = 19
- Plug 19 for x into either m∠6 or m∠7.
m∠6 = 7(19) - 24 = 109
m∠6 and m∠7 = <u>109°</u>
<em>__________________________________________________________</em>
21) m∠4 + m∠5 = 90 because they are complementary angles.
(2x - 5) + (4x - 13) = 90
6x - 18 = 90
6x = 108
x = 18
- Plug 18 for x into m∠4 and m∠5.
m∠4 = 2(18) - 5 = <u>31°</u>
m∠5 = 4(18) - 13 = <u>59°</u>

6.6-3.2 + =
First, Subtract <u>(6.6 - 3.2)</u>
<u>= 3.4</u>
<u>Then with the fraction</u><u>, add the result of the subtaction by the fraction:</u>
= 3.4 + , using happy face method

In this case we have 1/4 are green then (1/4) * 100 = 25. Then, 2/5 are yellow then (2/5) * 100 = 40. Therefore if the total number of skitles is 100, then the red skittles will be 100-40-25 = 35. There are 35 red skitles.
