so x=75 :)
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
Just divide the top of the fraction by the bottom, and read off the answer!
