(180 - 5x + 12) + x + 3x + 8 = 180
180 - x + 20 = 180
-180
-x + 20 = 0
- 20
-x = -20
x = 20
Sorry for the confusion! I believe this is the correct answer
<span>a = c+10
b = 2c
c = childs tickets cost $2 , so total for children would be c x $2.
adults tickets cost $5. so total for adults would be (c+10)*$5
so overall equation without seniors total would be $(c*2) + ((c+10)*5)</span>
111 hours is the answer. Hope is help.
The answer is -480 hope this helps
The angles are 45° 60° and 75°
Elaboration:
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
