Answer:
[2(x+10)]°+(3x-30)°=180°[vertically opposite angle]
2x+20+3x-30=180°
5x-10=180°
5x=180-10
5x=170
x=170/5
x=34
Answer:

Step-by-step explanation:
To know the steps pls look at the pic above
It’s C $12.75. You have to find 6% and add that on to $12.00
A = -0.7
B = -9/16 (0.5623)
C = -0.4
D = -5/16 (0.3125)
The last option is correct
Answer:
