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!

36x^2-21x-30 factor
miv72 [106K]
Easy...

to even begin to factor..you must factor out a 3, to simplify your answer.

3(12x^{2}-7x-10)

Now, you can factor.

3(12 x^{2} -7x-10)

So..to find the answer...

12*-10=-120x
and 
you would use -7x

What multiplies to -120..but adds to -7?

-15*8=-120
and
-15+8=-7

To find the answer, plug in what you know..

3(3x+2)(4x-5)

Thus, your answer.
