Hello there!
Start by seeing if there is an equal rate in the qmount of people that we are working with.
27/9=3 (so there's one)
3*45 (the amount of time when 9 people are in line)= 135 minutes

Answer:
9.58
Step-by-step explanation:
total score needed
9.5 * 5 = 47.5
Score from 4 judges
9.48 * 4 = 37.92
Score needed from 5th judge
47.5 - 37.92 = 9.58
Answer: - 25 < x < 5
Step-by-step explanation:The first thing is to Add 23 to both sides
The equation becomes
4 / x + 10 / < 37 + 23
4/x +10 / < 60
Divide through by 4
/ x +10/ < 15
to remove the modulus sign we have
-15< x + 10 < 15
we then solve one by one
firstly , - 15 < x + 10
subtract 10 from both sides
⇒ - 15 - 10 < x
-25 < x
solving the second part
x + 10 < 15
x < 15 - 10
x < 5
combining the two answers
-25 < x < x
