1:a would be 3. Subtract 9 & 6 to find 3. B= 7. Again 9-2 would help you find the answer. So then it would be 3+6=7+2.
2: 2+8 gets you 10. 10+5 gets you 15. 8+5 gets you 13. 2+13 gets you 15. So it’s 15=15.
3:7 needs to be changed into a fraction so, 7/1(1/7). Multiply across, you get 7/7, which gives you 1, so it’s 1=1.
4:I’m sorry I don’t know how to do this one
5:you multiply 3 and 6x, which gives you 18x. Then multiply 3 and 9y, and you get 27y. So then you have 18x+27y=18x+27y.
6: 15+0 gets you 15. So it’s 15=15.
Hope this helped. I’m not the best at explaining
Answer:
Step-by-step explanation:
∠ABD = 100
∠ABC + ∠CBD = ∠ABD
4x + 2 + 3x - 7 = 100
4x + 3x +<u>2 -7 </u>= 100 {Combine like terms}
7x <u> -5 </u> = 100
Add 5 to both sides
7x = 100 +5
7x = 105
Divide both sides by 7
x = 105/7
x = 15
∠CBD = 3x - 7
= 3*15 - 7
= 45 - 7
∠CBD = 48

-8-3=-5. there . thats the answer.
The slope of the red line would be the inverse of the green line. so the red line's slope is 1.
Green line: -1/1
Red line:1/1
