Question

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 solve it to describe the range of possible numbers

Answer 1

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!
