Answer : h = 10.5$
Explanation: since it says the total amount is 30$ then
The equation should all add up to 30$
And with the h= 10.5$
When we plug h in the equation we get:
30 = 15 + 2(10.5-3)
30 = 15 + 2(7.5)
30 = 15 + 15
30 = 30
-6z=12
z=-2

Answer:
- 7 singing acts
- 5 comedy acts
Step-by-step explanation:
If all were comedy acts, the 12 of them would take 36 minutes. To make the show last 14 minutes longer, there must be 7 singing acts, since each adds 2 more minutes to the show than does a comedy act.
There are 7 singing acts and 5 comedy acts in the show.
_____
If you need an equation, let s represent the number of singing acts. Then the show length is ...
5s +3(12 -s) = 50
2s + 36 = 50 . . . . . eliminate parentheses
2s = 14 . . . . . . . . . . subtract 36 (the time for 12 comedy acts)
s = 7 . . . . . . . . . . . . divide by 2. This is the number of singing acts.
12 -s = 5 . . . . . . . . . the rest of the acts are comedy acts
The fraction form is 11/25
Hope this helps!!!!:)
