The sum of a number times 7 and 21 is at least 29. Write as an inequality

PtichkaEL [24]

The inequality is 7x + 21 $\leq 29$

Step-by-step explanation:

DATA:

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

INEQUALITY:

7x + 21 $\leq 29$

SOLVE:

7x $\leq 29-21$

7x $\leq 8$

x $\leq \frac{8}{7}$

Therefore, the inequality is 7x + 21 $\leq 29$
