===============================================

Work Shown:

x = a number (something unknown)

3x = 3 times a number

3x+7 = the sum of 3 times a number and 7

4x = 4 times a number

3x+7 > 4x is the inequality that forms because the "the sum of 3 times a number and 7" portion is greater than the "4 times a number" portion

Answer:

(C)
3x + 7 > 4x

Explanation:

Let
represent the number that is unknown.

Using the words, we can write out each equation.

"The sum of three times a number and seven" will be adding 7 to 3x. So
3x + 7 .

"is greater than four times the number." will include a greater than sign and then 4 times the number, x. So:

> 4x

Combining these, we get
3x + 7 > 4x .

Hope this helped!
