Answer:

$m=\frac{y-b}{x}$

Step-by-step explanation:

So we have the equation:

$y=mx+b$

And we want to write it in terms of m.

So, let's subtract b from both sides:

$y-b=mx$

Now, let's divide both sides by x:

$m=\frac{y-b}{x}$

And we're done!

<h2>Answer:150 electricians,10 inspectors</h2>

Step-by-step explanation:

The solution uses unitary method.

The unitary method is a method for solving a problem by first finding the value of a single unit and finding the required value by multiplying the single unit value.

Given,

Each generator employs $3$ electricians.

Every $60$ electricians require $4$ inspectors.

So,every electrician require $\frac{4}{60}=\frac{1}{15}$ inspectors.

Anthony's department has $50$ generators.

Since each generator requires $3$ electricians, $50$ generators require $3\times 50=150$ electricians.

Since each electrician needs $\frac{1}{15}$ inspectors, $150$ electricians need $\frac{1}{15} \times 150=10$ inspectors.

So,to maintain peak performance Antony's department requires $150$ electricians and $10$ inspectors.

The probability that Caroline wins a raffle is given by the expression

RSB [31]

Answer: $\frac{n-m}{n}$

This is the same as writing (n-m)/n

Don't forget about the parenthesis if you go with the second option.

==================================================

Explanation:

The probability that she wins is m/n, where m,n are placeholders for positive whole numbers.

For instance, m = 2 and n = 5 leads to m/n = 2/5. This would mean that out of n = 5 chances, she wins m = 2 times.

The probability of her not winning is 1 - (m/n). We subtract the probability of winning from 1 to get the probability of losing.

We could leave the answer like this, but your teacher says that the answer must be "in the form of a combined single fraction".

Doing a bit of algebra would have these steps

$1 - \frac{m}{n}\\\\\frac{n}{n} - \frac{m}{n}\\\\\frac{n-m}{n}\\\\$

and now the expression is one single fraction.
