Answer:
x=12
Step-by-step explanation:
The three angles add to a straight line which is 180 degrees
20 + 6x-2 + 90 = 180
Combine like terms
108 + 6x = 180
Subtract 108 from each side
108+6x-108 = 180-108
6x =72
Divide each side by 6
6x/6 = 72/6
x=12
Answer:
8x+4 and 10x+4
Step-by-step explanation:
Using the distributive property, you times 8 by x and then 8 by one half: 8x & 8*1/2. 8x+4
You then do the same for 10(x+2/5): 10x and then 10 divided by 5 and times by 2. This leaves you with 10x+4.
I hope this helped. :)
Answer:
The slope would also be 2/7.
Step-by-step explanation:
The two lines are parallel, meaning that they follow the same slope. If line / has a slope of 2/7, then line M must have the same slope as well. I hope this helps! :)
