Question

Which of the following statements about a variable are true?

a, A variable is represented by a letter.
b, A variable cannot be subtracted.
c, A variable represents a quantity.
d, A variable cannot be multiplied.

Answer 1

The answer is "A variable represents an unknown quantity"

Explanation:

For example 3b-5=25

To answer this question you would need to find the variable. The variable is b. we know this because tho get 60 you would need to multiply 3 and b and your answer is 25 so that means before you subtract 5 your answer would be 30. meaning b=10 because 10x3=30. b=10

Answer 2

Both A and C are correct but I mostly agree with C
