A number line. like where u plot the points (usually numbers) to compare them.
Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.
Add like terms to get 5x - 20 = 180
5x = 200
x = 40
Multiplying with 6 is like multiplying with 3 because, you just double it. Let's say 3 × 4 = 12
Its the same as 6 × 2 = 12 ... which is just 3 + 3 + 3 + 3 . ((:
The answer is C it is the amount of money divided equally between each student
4(x-1)=1/2(x-8)
First, distribute.
4x-4=1/2x-4
Subtract 1/2x from both sides.
7/2x-4=-4
Add 4 to both sides.
7/2x=0
Divide both sides by 7/2.
x=0
The answer is x=0.
Hope this helps :)
