7(x - 3) = 4(x + 5)
7(x) - 7(3) = 4(x) + 4(5)
7x - 21 = 4x + 20
- 4x - 4x
3x - 21 = 20
+ 21 + 21
3x = 41
3 3
x = 13²/₃
9(x - 2) = 18
9(x) - 9(2) = 18
9x - 18 = 18
+ 18 + 18
9x = 36
9 9
x = 4
17x - 6 + 3x - 5 = x + 11 + 4x
17x + 3x - 6 - 5 = x + 4x + 11
21x - 11 = 5x + 11
- 5x - 5x
16x - 11 = 11
+ 11 + 11
16x = 22
16 16
x = 1³/₈
Answer:
angles 1 and 2 are not congruent (A)
Step-by-step explanation:
They are supplementary angles. The only way for supplementary angles to be congruent is that they both are equal to 90 degrees. We can see in this figure that they are not right angles. Therefore, we can conclude they are not congruent. HTH :)
