Answer:
x=-5
x+85 = 80 degrees
x+105= 100 degrees
Step-by-step explanation:
(x+85)+(x+105)=180 since it is a straight line
2x+190=180
2x=-10
x=-5
so x+85 = 80 degrees
x+105= 100 degrees
Answer:
x+85 + x+105 = 180
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
Step-by-step explanation:
The two angles form a straight line so they add to 180
x+85 + x+105 = 180
Combine like terms
2x + 190 = 180
Subtract 190 from each side
2x+190-190 = 180-190
2x = -10
Divide by 2
2x/2 = -10/2
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100

Just substitute
0.5(30)+5 =20
7+2y=8
3x-2y=0
7+2y=8
y=8/3
3x-2(8/3)=0
3x-16/3=0
+16/3 +16/3
3x=16/3
/3 /3
x=16/9

Answer:
-3.09 per hour
Step-by-step explanation:
if you mean that it went down from 0° to -131.5° in 42.5 hours, divide -131.5 by 42.5 (-131.5/42.5) which gives 3.09
