Which list shows three solutions to the inequality?
x + 7 < 30
There are infinitely many solutions to this inequality, but here are three examples:
1) x < 23
2) x can be any number between -7 and 23, inclusive
3) x = 22.5
To solve the inequality x + 7 < 30, we need to isolate x. Here are three possible steps to do so:
Step 1: Subtract 7 from both sides of the inequality:
x + 7 - 7 < 30 - 7
x < 23
Step 2: Rewrite the inequality in a simpler form:
x < 23
Step 3: Choose three values less than 23 to substitute for x and check if they satisfy the inequality. For example:
-10 < 23
0 < 23
15 < 23
Therefore, three possible solutions to the inequality x + 7 < 30 are x < -10, x < 0, and x < 15.
