1) Sketching it
Since the line segment AD = 10x -5 and AC= 3x +1 and CD= 15
According to the Segment Addition postulate we can write:
3x+1+15=10x-5 <em>Combining like terms</em>
3x +16 = 10x -5 <em>Subtract 16 from both sides</em>
3x = 10x-5-16 Subtract 10x from both sides
3x-10x =-21
-7x = -21
7x=21 <em>Dividing by 7 on both sides</em>
x=3
Answer:
-7/13
Step-by-step explanation:
(1 + 7x) - 6 * (-7 - x) = 36 Distribute the 6 into (-7 - x)
1 + 7x + 42 + 6x = 36 Combine like terms (1 + 42) & (7x + 6x)
43 + 13x = 36 Subtract 43 from both sides
13x = -7 Divide by 13
x = -7/13
