1Which of the following is a variable?
Show Answer+
Answer: x
Hint: A variable is a letter that can take different values.
Solution:
A variable is a symbol (usually a letter) that represents an unknown or changing quantity.
Here, x is a variable. The rest (5, 7 + 3, 12) are all constants.
2Which of the following is a constant?
Show Answer+
Answer: 8
Hint: A constant has a fixed value that does not change.
Solution:
A constant is a quantity whose value is fixed.
8 is a fixed number, so it is a constant. The letters a, n, and p are variables.
3What is the algebraic expression for 'a number x increased by 5'?
Show Answer+
Answer: x + 5
Hint: 'Increased by' means we add to the number.
Solution:
'A number x increased by 5' means we add 5 to x.
The algebraic expression is: — x + 5
4How many terms are there in the expression 3a + 7b - 2?
Show Answer+
Answer: 3
Hint: Terms are separated by + or - signs.
Solution:
In the expression 3a + 7b - 2, the terms are separated by + and - signs.
The three terms are: 3a, 7b, and 2.
5What is the coefficient of x in the term 9x?
Show Answer+
Answer: 9
Hint: The coefficient is the numerical part multiplied with the variable.
Solution:
In the term 9x, the number 9 is multiplied with the variable x.
The coefficient of x is 9.
6What is the value of x + 3 when x = 4?
Show Answer+
Answer: 7
Hint: Replace x with 4 and then add.
Solution:
Substitute x = 4 into the expression x + 3.
x + 3 = 4 + 3 = 7 — 4 + 3 = 7
7Which of the following represents 'twice a number y'?
Show Answer+
Answer: 2y
Hint: 'Twice' means two times the number.
Solution:
'Twice a number y' means 2 multiplied by y.
The expression is: — 2y
8Solve: x + 6 = 10. What is the value of x?
Show Answer+
Answer: 4
Hint: What number added to 6 gives 10?
Solution:
We need to find x such that x + 6 = 10.
Subtract 6 from both sides: — x = 10 - 6 = 4
9Which pair are like terms?
Show Answer+
Answer: 5a and 7a
Hint: Like terms have the same variable part.
Solution:
Like terms are terms that have the exact same variable(s).
5a and 7a both contain the variable 'a', so they are like terms.
10What is the algebraic expression for '7 subtracted from a number n'?
Show Answer+
