Answer:
-3x - 7 is the furthest it can be simplified
Answer:
21 child tickets
Step-by-step explanation:
For this problem, you'd use a system of equations.
First, define your variables.
x = # of child tickets sold
y = # of adult tickets sold
There were 4 times as many adult tickets (y) as child tickets (x) sold, so:
4 x = y
4 x - y = 0
93 (4 x - y = 0)
372 x - 93 y = 0
The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:
6.10 x + 9.30 y = 909.30
10 (6.10 x + 9.30 y = 909.30)
61 x + 93 y = 9093
372 x - 93 y = 0
433 x = 9093
433 x / 433 = 9093 / 433
x = 21
Answer:
The number of kids NOT wearing socks in the gym = 20
Step-by-step explanation:
Here, the total number of kids in the gym = 80
Now, 75% of the kids are wearing socks.
Let us assume the number of kids wearing socks = m
⇒ 75 % of 80 = m
Calculating the value of m ,we get:

⇒ 60 kids are wearing socks.
Kids not wearing socks = Total kids in gym - Kids wearing socks
= 80 - 60 = 20
Hence, the number of kids NOT wearing socks in the gym = 60.
