Simplify both sides of the equation
(20)(4)= 4(5x+1)
Simplify
80 = 20x+4
Flip the equation
20x+4 = 80
Subtract 4 from both sides
20x+4-4 = 80-4
20x = 76
Divide both sides by 20
20x/20 = 76/20
x= 3.8
There is one solution in this equation

Step-by-step explanation:
The average fraction of students in the two classes who went on the field trip is 11/16
<h3>What is the average fraction of students in the two classes who went on the field trip?</h3>
The given parameters are:
Class 1 = 3/4
Class 2 = 5/8
The average is calculated as
Average = 1/2 * (Class 1 + Class 2)
So, we have
Average = 1/2 * (3/4 + 5/8)
Evaluate
Average = 11/16
Hence, the average fraction of students in the two classes who went on the field trip is 11/16

Answer:
$5.40
Step-by-step explanation:
To find the increase we need to consider our variables.
Current Rate = $4.50
Increase Percentage = 20% or 0.20
Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.
Total Price w/ Increase = ($4.50 x 0.20) + $4.50
Total Price w/ Increase = $0.90 + $4.50
Total Price w/ Increase = $5.40
