2. a
3. a
Step-by-step explanation:
To find the combined terms, focus only on the terms that have the same variable value. See the examples below.
1.
7 + 19t - 6t
7 + (19t - 6t)
7 + 13t
2.
5/6x - 2/3x
(5/6x - 2/3x)
1/6x
3.
8 + 16r - 9r
8 + (16r - 9r)
8 + 7r
Answer:
21
Step-by-step explanation:
you plug in 5 for a and 6 for b and solve.
106,127,129,132,135,138,140,158
132 + 135 = 267
267/2 = 133.5
Median is 133.5
Answer:
a= 52
Step-by-step explanation:
82 + (x+60) + (x+54) = 180
82 + 2x + 114 = 180
2x + 196 = 180
2x = -16
x = -8
plug in -8 in x +60
-8 + 60 = 52
a = 52
