Answer:
8
Step-by-step explanation:
15x-31+9×+11+×=180
25×-20=180
25×=200
×=8
15(8)-31=89
9(8)+11=83
(6-2)×180 = 720
101+154+72+123+145+x=720
595 + x = 720
x = 720-595
x= 125
The answer is 0
C= 25$ + 50$ * h
8 hours 425$
10 hours 525$
a = 62
The sum of the angles of a triangle is 180 degrees
a + 47+71 = 180
Combine like terms
a +118 = 180
Subtract 118 from each side
a+118-118=180-118
a =62
