Diego’s history teacher writes a test for the class with 26 questions. The test is worth 123 points and has two types of questions: multiple choice worth 3 points each, and essays worth 8 points each.
How many essay questions are on the test? Explain your reasoning.
Answer: 9 essay questions
Step-by-step explanation:
The test has 26 questions
The test is worth 123 points
The test has two types of questions:
Multiple choice worth 3 points each
Essays worth 8 points each
Let the number of multiple choice questions be, m, and the number of essay questions be , e.
This forms a simultaneous equation below:
m + e = 26 ... (i)
3m + 8e = 123 ... (ii)
Multiplying (i) by 3 and (ii) by 1 we get:
3m + 3e = 78 ... (i)
3m + 8e = 123 ... (ii)
Subtracting (ii) - (i) we get;
0m + 5e = 45
5e = 45
e = 45 ÷ 5 = 9
So there are 9 essay questions.
and;
m + 9 = 26
m = 26 - 9 = 17
There are also 17 multiple choice questions.

Which of the following correctly shows clustering for the problem 72 x 13?
72 x 10 + 72 x 3
72 x 12 + 72 x 1
70 x 10 + 2 x 3
72 x 10 + 72 x 13
72×10+72×3 and 72×2+72×1 shows clustering for the problem 72 x 13
What is Number system?A number system is defined as a system of writing to express numbers.
The given expression is 72 x 13.
Seventy two times of thirteen.
We can write this 72×(10+3)
By distributive property
72×10+72×3
So 72×10+72×3 shows the clustering for the problem 72 x 13.
and we can also write this as given 72×(12+1)
72×2+72×1 also shows the clustering for the problem 72 x 13.
Hence, 72×10+72×3 and 72×2+72×1 shows clustering for the problem 72 x 13
