<u>Answer:</u>
9. x = 12
10. x = 31
<u>Step-by-step explanation:</u>
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
<u>Check:</u>
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
<u>Check:</u>
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

♡ The Explanation/Step-By-Step ♡
-
6/100 + 5/100 + 80/100 + 9/100
Apply the fraction rule! --> a/c + b/c = a + b over c
6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100
Add the numbers: 6 + 5 + 80 + 9 = 100!
= 100/100 Apply the fraction rule! a/a = 1
a/a = 1 = 100/100 = 1
