(a) The equation
First, we calculate the slope (m)

From the table, we can say that:


So, we have:




The equation is then calculated using:

This gives:




(b) When x = 54
Substitute 54 for x in 


A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.
6 x 7 = 42
Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.
42 x 20 = 840
Hence, there are 840 bolts in 20 appliances.
There are 20 cassettes.
Step-by-step explanation:
Given,
Ratio of cassette to compact disc = 10:3
Let,
the number of cassettes = 10x
Number of compact disc = 3x
According to given statement;
the number of cassettes is 10 less than 5 times the number of compact discs.
10x = 5(Number of CD) - 10

Dividing both sides by 5

Number of cassettes= 10x = 10(2) = 20
There are 20 cassettes.
