Which list shows three solutions to the inequality?
x + 7 < 30
A. 24, 25, 25
B. 20, 25, 30
C. 13, 17, 19
D. 15, 22, 29
D. 15, 22, 29
To find three solutions to the inequality x + 7 < 30, we can subtract 7 from both sides of the inequality to isolate x.
Subtracting 7 from both sides, we get:
x < 30 - 7
Simplifying, we have:
x < 23
Now to find three solutions, we can choose three different values for x that are less than 23.
Looking at the options, the list that shows three solutions to the inequality x + 7 < 30 is:
D. 15, 22, 29
