5x + 20 = 90 - a = 90 - (3x + 40)
5x + 20 = 90 - 3x - 40 = 50 - 3x
5x + 3x = 50 - 20
8x = 30
x = 30/8 = 15/4
b = 3(15/4) + 40 = 45/4 + 40 = 51.25
The measure of a supplementary angle is 180 - 51.25 = 128.75
Answer:
answer
Step-by-step explanation:
you have to subtract 3b from 3a so the answer is 0.
Answer:
From greatest to least
One and five-sixth rounded to 2
One and StartFraction 7 over 29 rounded to 1
0.16 rounded to 0
Step-by-step explanation:
1+7/29=29+7/29
=36/29
=1.24
Approximately
=1
1+5/6=6+5/6
=11/6
=1.83
Approximately
=2
0.16
Approximately =0
From greatest to least
