Answer:
x = 5, y = 20
Step-by-step explanation:
Since AB and CD are parallel, then
∠ AOC and ∠ OCD are Alternate angles and congruent, thus
12x + 8 = 68 ( subtract 8 from both sides )
12x = 60 ( divide both sides by 12 )
x = 5
-------------------------------
∠ OCD and 5y + 12 are adjacent angles and supplementary, thus
5y + 12 + 68 = 180 , that is
5y + 80 = 180 ( subtract 80 from both sides )
5y = 100 ( divide both sides by 5 )
y = 20
<u>4x+8:</u>
9x+2-5x+6
2x+1+2x+7
<u>-4x-8</u>
-7x-10+3x+2
-7x-10+3x+2
<u>4x-8:</u>
-x+5+5x-13
-2x-7+6x-1
Step-by-step explanation:
We will have to solve each expression to see to which category it belongs
So,
1. 9x+2-5x+6

2. -2x-7+6x-1

3. 2x+1+2x+7

4. -6x+2+2x-10

5. -x+5+5x-13

6. -7x-10+3x+2

Hence,
<u>4x+8:</u>
9x+2-5x+6
2x+1+2x+7
<u>-4x-8</u>
-7x-10+3x+2
-7x-10+3x+2
<u>4x-8:</u>
-x+5+5x-13
-2x-7+6x-1
