Do 27 - 10 = 17∠ 10
Your welcome
The answer is D.
Find common factors of denominators.
15+10+4/20= 29/20= 1 9/20 :)
The first option because turn them all into degrees and it says:
54, 60, 90, 120, 255
The answer would be (3,-1)
You divide -15 on both sides to keep the x alone
-240/ -15=16
A negative divided by a negative is a positive so x=16
