Answer:

615 = 68x + 238

Step-by-step explanation:

You have to set the equation equal total miles and to find the time you multiply the amount of remaining hours (x) by the miles per hour and then add the miles already traveled. To find the value of x do simple algebra and isolate x on one side of the equation by subtracting 238 from both sides and then dividing both sides by 68.

K=m-n÷y (make y the subject)​
Mkey [24]

Answer:

y = \frac{n}{K - m}

Step-by-step explanation:

When doing problems like these, you should go through the process like using PEMDAS:

P - Parenthesis ()

E - Exponents x^{2}

M - Multiply x

D - Division ÷

A - Addition +

S - Subtraction -

1) Since there aren't any Parentheses, or exponents, we should then check for any use of Multiplication.

As shown, there are no shown methods of multiplying.

BUT there is Division, so we will do the opposite of division, which is multiplication.

K = m - n ÷ y

y(K = m - n ÷ y)y

^ Trying to multiply 'y' onto both sides, because when you do something to one side, you do to the other. ^

'y' then cancels out on one side, so you will be left with:

= m - n

But on the other side you will have:

Ky

So your problem will look like:

Ky = m - n

2) Since we are trying to get 'y' by itself, instead of multiplying now, we will be dividing, because:

K(y) = Ky  or you can also say K x y = Ky

Back to the problem, we will now divide 'K' to both sides, as stated before:

What you do to one side, you do to the other:

\frac{Ky}{K} = \frac{m - n}{K}

'K' will cancel out on one side:

\frac{Ky}{K} = y

Leaving you with:

'y'

While the other side, will be left as:

\frac{m - n}{K}

So your final answer will be:

y=\frac{m - n}{K}

A company policy requires that for every 30 employees, there must be 3 supervisors. If there are 267 supervisors at the company,
Alexus [3.1K]

267 supervisors will have 2670 employees.

Step-by-step explanation:

Let x be the number of employees.

Given,

3 supervisors = 30 employees

1 supervisor = \frac{30}{3}

1 supervisor = 10 employees

As one supervisor has 10 employees, 267 supervisors will have;

x = 267*10

x= 2670 employees

267 supervisors will have 2670 employees.
