IXL | Solve one-step addition and subtraction inequalities: word problems

Miles read 4 books in the first half of March. By the end of March, the library had added Miles to the top-readers board for reading more than 10 books in a month.

Let

represent how many books Miles read in the second half of March. This inequality describes the problem.

Which algebra tiles model this inequality?

Solve the inequality. Then, complete the sentence to describe the solution.

question

It takes at least 9 players to form a baseball team. So far, 5 players have joined the Blue Jays baseball team.

Let

represent how many more players need to join. This inequality describes the problem.

≥

Which algebra tiles model this inequality?

Solve the inequality. Then, complete the sentence to describe the solution.

At least more players need to join.

solution

The inequality

≥

describes the problem. The expression

represents the total number of players on the team after more join. That needs to be at least 9.

You can model the inequality using algebra tiles.

The left side of the inequality is
5
+
x
.
So, the left side of your answer should have 1
x
-tile
and 5 1-tiles.
The right side of the inequality is 9. So, the right side of your answer should have 9 1-tiles.

These algebra tiles model the inequality

≥

To solve for

remove 5 1-tiles from each side.

≥

Simplify.

≥

The solution to the inequality is

≥

So, at least 4 more players need to join.
