Question

5x - 1 can be represented by:

a. The difference of 1 and a number x.
b. The sum of 5 times a number x and 1.
c. One less than five times a number x.
d. The product of 5 and a number x, decreased by 1.

Answer 1

5x - 1 can be represented as one less than five times a number x.

Step-by-step explanation:

5x - 1 can be represented as c. One less than five times a number x. To understand why, let's break down the expression:

1. 5 times a number x is represented as 5x.
2. When we subtract 1 from 5x, it becomes 5x - 1.
3. Therefore, 5x - 1 is one less than five times a number x.

For example, if x represents 3, then 5x - 1 would be 5(3) - 1 = 15 - 1 = 14.
