Let’s go through each question one by one and solve them carefully.
---
Question 1: The number before a variable is the ___.
In algebra, when you see something like “5x”, the number 5 is called the
coefficient. It tells you how many of that variable you have.
✔ Correct answer:
B) coefficient
---
Question 2: A letter that represents a number is called a ___.
Letters like x, y, or a are used to stand for unknown numbers — these are called
variables.
✔ Correct answer:
B) variable
---
Question 3: What do you call each part of an expression that is separated by a + or a -?
For example, in “3x + 5 – 2y”, the parts are “3x”, “+5”, and “–2y”. Each of these is called a
term.
✔ Correct answer:
D) term
---
Question 4: What is the coefficient in the expression: 94a + 2?
The coefficient is the number multiplied by the variable. Here, “94a” means 94 times a, so the coefficient is
94.
Note: “2” is a constant (no variable), and “94a” is a term, not just the coefficient.
✔ Correct answer:
D) 94
---
Question 5: In the expression 4x - 12, what is 4x?
“4x” is one complete part of the expression — it includes both the coefficient (4) and the variable (x). So it’s called a
term.
✔ Correct answer:
B) term
---
**Question 6: How many terms are in the following expression?
7y + 3 - 7k - 2**
Break it down:
- 7y → term 1
- +3 → term 2
- -7k → term 3
- -2 → term 4
Even though some are being subtracted, they’re still separate terms.
So total =
4 terms
✔ Correct answer:
A) 4
---
Now let’s compile all answers clearly.
Final Answer:
1. B
2. B
3. D
4. D
5. B
6. A
