What algebraic expression represents this?: 71 less than three times a number.

Answer 1

When approaching this problem there are two things to take note of. First is "71 less than". This implies that you will be subtracting 71 from a number. The second is " 3 times a number " which implies you will be multiplying a variable by 3.

Let's set our variable as x.

We first must multiply by 3, and then subtract 71 from it. This gives us our answer:

3x-71

Answer 2

Question:

4. Combine the expression 3x-71
5. The complete algebraic express is 3x-71

Solution:

The algebraic expression is 3x-71

Answer 3

1. "71 less than" indicates something has decreased by 71
2. "three times a number" indicates 3 is multiplied by an unknown number, before being decreased by 71. I chose "X" to indicate the unknown number.
3. So, 71 less than three times a number can be represented in algebraic form as: 3X-71

Answer 4

The algebraic expression for "71 less than three times a number" can be written as:

3x−71

Here:

1. x represents "a number."
2. "Three times a number" is 3x.
3. "71 less than" means we subtract 71 from 3x.
