Answer 1

Answer:

Option 1)

$n+15-15<22-15$

Option  3)

$n+15-22 <22-22$

Option 4)

$n+15+6 <22+6$

Step-by-step explanation:

We are given an inequality in the question:

$n+15 <22$

We have to find the inequalities equivalent to the given inequality.

1)

$n+15-15<22-15\\n + 15 < 22-15 + 15\\n +15 < 22$

which is equivalent to the given inequality.

2)

$n+15<22-15\\n +15 < 7$

which is not equivalent to the given inequality.

3)

$n+15-22 <22-22\\n+15 < 22-22+22\\n +15 < 22$

which is equivalent to the given inequality.

4)

$n+15+6 <22+6\\n +15 < 22+6-6\\n+15 < 22$

which is equivalent to the given inequality.

5)

$n+15-22 <22\\n+15< 22+22\\n+15<44$

which is not equivalent to the given inequality.
