Answer:

250 - 20 < 80 + 15x

Step-by-step explanation:

Given that

Beth has 250 books and 20 books sold each week

While on the other hand, Martin has 80 books and sell 15 books each week

Let us assume each week be x

Now the equations are

Beth 250 - 20x

Martin 80 + 15 x

Now the inequality would be

Step-by-step explanation:

Inequality: 48+12b≥185

Why? she has already backed 48 cookies so you just need to find how many more she needs to bake. (she doesn't need 185 cookies anymore since she's already baked 48)

You don' t need to solve the question,

But here is how you do...

12b≥137

b≥11.42 (roughly)

Answer:

We call the denominator rational.

Step-by-step explanation:

For example:

$\frac{1}{\sqrt{2}} = \frac{\sqrt2}{\sqrt2 \cdot \sqrt2} = \frac{\sqrt2}{2}$

It's clear that the denominator is now a rational number, not an irrational one anymore.
