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
