Answer:
that x is represented by 3 as the value
Step-by-step explanation:
He puts 15 markers in the box. Hope this helps.
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
21/10 divided by 2 4/5 represents the time spent on a shift
<h3>How to determine what 21/10 divided by 2 4/5 represent in this situation?</h3>
The given parameters are
Time = 21/10
Shifts = 2 4/5
This means that:
21/10 divided by 2 4/5 represents:
Time/Shift
i.e. time per shift
Hence, 21/10 divided by 2 4/5 represents the time spent on a shift
