Day 60 - 8.PFA.5 Practice Test: Solving MS Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '>' mean in an inequality?

Back

The symbol '>' means 'greater than'. It indicates that the value on the left side of the inequality is larger than the value on the right side.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. It indicates that the value on the left side of the inequality is smaller than the value on the right side.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'. It indicates that the value on the left side is either larger than or equal to the value on the right side.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'. It indicates that the value on the left side is either smaller than or equal to the value on the right side.

Front

How do you solve the inequality -3 - 6(4x + 6) > -111?

Back

First, distribute -6: -3 - 24x - 36 > -111. Combine like terms: -24x - 39 > -111. Add 39 to both sides: -24x > -72. Divide by -24 (remember to flip the inequality): x < 3.

Front

What inequality represents Joan's babysitting situation?

Back

5x + 10 ≥ 100, where x is the number of hours she babysits.

Front

How do you express the growth of a willow tree in an inequality?

Back

5.1 + 2.5y ≤ 60, where y is the number of years.

Front

What does the inequality 15 + 6x ≤ 100 represent in a real-world context?

Back

It represents the maximum number of people Andrea can invite to play laser tag, given the cost structure.

Front

How do you match a graph with its inequality?

Back

Identify the boundary line and the region it represents. For example, 4(b+3) - 6 ≤ -2 indicates a shaded region below the line.
