Answer:

Let x be the number

"five times a number"

5x

"six less than five times a number"

5x-6

"is at least 29" >29 (greater than or equal too)

5x - 6 > 29

5x > 35 (add +6 to both sides retains the dense if the inequality)

x>7 (divide both sides by +7 retains the sense of Inequailty)

Check:

Is 5(7) - 6 > 29?

35 - 6 > 29 ?

29 > 29? yes, they are equal.

Try 50:

Is 5(50) - 6 > 29 ?

250 - 6 > 29?

244 > 29 ? yes

Answer:

5x - 6 = 29
