"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that
a = kb
We're given that a = 18 and b = 3, so that
18 = 3k ⇒ k = 6
Then when b = 5, we would have
a = 6 × 5 = 30
It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.
<h3>How to calculate the hourly delivery rate</h3>
Your information is incomplete. Therefore, an overview of the information will be given.
In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.
In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:
= $2000/240
= $8.33 per hour

The area of a rectangle is length*width.
The length of this 3x and the width is 2x-3. This means that, to find the area, you need to multiply 3x and 2x-3.
Start by writing out this equation:
A=l*w
Then, plug in your given values:
A= 3x*2x-3 (you can also write it as A= 3*x*2*x-3)
Then, following the order of operations, you start by multiplying. This makes your equation become A = 6x^2 -3. (^2 means squared). It turns into this because 3 * 2 is 6 and x * x is x^2 and you still haven’t used the 3 yet.
After this, there is nothing more that you can do to simplify the equation. Therefore, the area is 6x^2 - 3.
