Answer:
x = 9
Step-by-step explanation:
when two lines intersect, it creates four angles. vertical angles are the angles that are opposite to each other. in the attached image, 1 & 3 are vertical angle pairs, and so are 2 & 4.
since vertical angles are always congruent, 3x - 8 is equal to 2x + 1
3x - 8 = 2x + 1
add 8 to each side
3x = 2x + 9
subtract 2x from each side
x = 9
check your answer:
3x - 8 = 2x + 1
3(9) - 8 = 2(9) + 1
27 - 8 = 18 + 1
19 = 19
Answer:
x = 11
Step-by-step explanation:
So the equation is 25x = 275. In order for us to find out what x is we need to get rid of 25 that is next to x, so we are going to have to divide 25x by 25. What you do to one side you do to the other so the equation will look like this:
25x/ 25 = 275/ 25
25x/25 = x
275/25 = 11
so x = 11
Answer:
<em>-13x +8y</em>
Step-by-step explanation:
-5x+2y-8x+6y
rearranging;
-5x-8x+2y+6y
(-5x-8x)+(2y+6y)
(-13x)+(8y)
I got you :)
-2x + 8 = 22
Subtract 8 from both sides....
-2x = 14 Divide by 2 on both sides....
<h2><u>x = -7</u></h2>
