Answer:

Step-by-step explanation:

We need to change the English writing into an inequality.

We know that a number "n" added to 7 is less than or equal to 9.

This can be written as follows:

n + 7 ≤ 9

Now, we will isolate the "n" at one side of the inequality. We will do this by subtracting 7 from both side as follows:

n + 7 - 7 ≤ 9 - 7

n ≤ 2

Answer:

n+7≤9 or n≤2

Step-by-step explanation:

A number= n

plus 7= +7

less than or equal to=≤

9= 9

n+7≤9

n+7-7≤9-7

n≤2
