Answer: 8 weeks
The range of the averages in a class with a maximum point of 100 point and a minimum point of 20 point is 80 points
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Range is the difference between the maximum value and minimum value of a data set. Hence:
Range = Maximum - Minimum
Let us assume that the maximum point is 100 point and the minimum point is 20 point, hence:
Range = 100 - 20 = 80 points
The range of the averages in a class with a maximum point of 100 point and a minimum point of 20 point is 80 points

Answer: x=1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x+2*(5*x-3)-(7)=0
3x + 2 • (5x - 3)) - 7 = 0
Pull out like factors :
13x - 13 = 13 • (x - 1)
13 = 0
A a non-zero constant never equals zero.
Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1
Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
