Step-by-step explanation:
x+77=126 (vertical opposite angles are equal)
x=126-77
x= 49
Answer:
slope = 5/8
Step-by-step explanation:
y2 - y1 / x2 - x1
-7 - (-2) / -3 - 5
-5 / -8
= 5/8
The answer is -40 because 1/2 of 4 is 2 and 1/2 of 5 is 2.5, 2•2.5=5. -2•-2•-2=-8. 5•-8=-40
Answer:
1) -5b + 16
2) -5a
3) 7a - 12
4) 7 + 4x
5) x + 6
6) 7a + 3
7) 11x + 2
8) 9x - 8
9) -13n
10) 18b -5
Step-by-step explanation:
Combine like terms for a simplified expression.
(Example: x + 2x = 3x and 3 - 8 = -5)
