Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We have

Substitute:

Convert to the slope-intercept form

<em>use the distributive property</em>
<em>add 3 to both sides</em>

Convert to the standard form

<em>multiply both sides by 3</em>
<em>add x to both sides</em>

Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
Answer:
20
Step-by-step explanation:
Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.
