Question

Which values from the set {2, 4, 6, 8, 10) make the inequality n +5 > 10 true?

Answer 1

Answer:

6, 8, 10

Step-by-step explanation:

First, solve the inequality

To do this, we need to get n by itself

n +5 > 10

5 is being added to n. To undo this, subtract 5 from both sides, since subtraction is the opposite of addition. This will eliminate the 5 on the left side, and leave n by itself.

n+5-5 > 10-5

n > 5

So, any number greater than 5 is a solution, and will make the inequality true.

The numbers in the set that are greater than 5 are 6, 8, and 10

To test that these numbers do make the inequality true, substitute each value in for n

n +5 > 10

6+5 > 10

11 > 10

True

n +5 > 10

8+5>10

13>10

True

n +5 > 10

10+5> 10

15>10

True
