I’m thinking of a number. When you multiply it by 3 and subtract 10 you will get a number less than 5. Form an inequality and so
sweet-ann [11.9K]

Answer:

3x-10

Step-by-step explanation:

Let x be equal to the number.

We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:

3x-10

To find the range of possible values, we must solve the inequality and isolate x.

3x-10

Add 10 to both sides

3x-10+10

Divide both sides by 3

\frac{3x}{3}

I hope this helps!
