A division problem which this model represent include the following: 24 ÷ 8 = 3.
In order to evaluate and solve this expression, we would have to apply the PEMDAS rule, where mathematical operations within the parenthesis (grouping symbols) are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the equation to the right.
Lastly, the mathematical operations of addition or subtraction would be performed from left to right.
Note: Let the variable x represent each of the boxes.
Based on the model provided below, we have the following mathematical expression:
x + x + x = 24
3x = 24
x = 24/3
x = 8
Therefore, the division problem is given by;
24 ÷ 8 = 3.

Complete Question:
What division problem does this model represent?
Answer:
See explanation
Step-by-step explanation:
Width = 25 seconds
Lower class limit = 125 seconds
To find the frequency of each class, just count the numbers which appear in described class
Hence, the frquency distibution is
Classes: Frequency
125 - 150 seconds 1
151 - 175 seconds 0
176 - 200 seconds 0
201 - 225 seconds 4
226 - 250 seconds 34
251 - 275 seconds 11

Answer:
B. The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
Let us first find the solution to the system of equations.
x+y= 24
3x+5y= 100
We use substitution method.
x=24-y
Replacing the value of x in the second equation.
3(24-y)+5y=100
Then solve for y.
72-3y+5y=100
2y=100-72
2y=28
y=14
To find x let us replace the value of y in x=24-y
x=24-14
x=10
This means that the test has 14 five-point questions and 10 three point questions.
