Question

Help me please cause i dont understand i really need this question right know ill give you 20 points if you help me

Answer 1

Step-by-step explanation:

Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1

Answer 2

Answer:

x < 2 or (-∞,2)

Step-by-step explanation:

Treat the inequality sign like an = sign at this point. Don't make it more complicated than it really is. So, to figure it out, you first need to divide each side by 15 so you can get x all by itself:

$\frac{15x}{15} < \frac{30}{15}$

Now we have:

x < $\frac{30}{15}$

We know (using simple math) that 30 divided by 15 is 2, which gives us:

x < 2.

In interval notation, this would be (-∞,2). [Remember that the parentheses show that the interval does NOT include the specified numbers, which is what < denotes in our equation.] Hope this helped!
