A person's hourly pay rate, r, is found by dividing the total amount
marishachu [46]

Translating the words into formula, we have

r = \dfrac{p}{w}

In fact, we have that the pay rate is the total payment divided by the number of hours worked.

We can solve this formula for w in two steps: starting from the formula above, multiply both sides by w:

rw = p

And then divide both sides by r:

w = \dfrac{p}{r}

Try to subtitute y with 3x - 7
15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
35 ≠ 14

Solve 5x^2 +16x -84=0 using the quadratic equation
Andrew [12]
In order to find the answer to this question, we need to use the quadratic formula. 

-b +- √b² - 4ac
      2a

In this equation, 5 is a, 16 is b, and -84 is c. You'll notice that the formula says 'plus or minus', meaning that there are two answers depending on whether you add or subtract. Let's start by adding.

-16 + √16² -(4(5)(-84)
         2(5)

Use a calculator to simplify. Remember PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction) when deciding which order to go in.

-16 + 44
      10
2.8

One solution is 2.8. Now, let's do the same thing, but subtract this time. Keep in mind that the number under the radical stays the same, so you don't have to recalculate that.

-16 - 44
     10
-6

The solutions to the equation are 2.8 and -6.

Hope this helps!

You are driving in France and see the price of gasoline is 2.099 euros per liter. Use the facts below to calculate the price in
Dahasolnce [82]

Answer: \$10.503

Step-by-step explanation:

Knowing that the price of gasoline in France is 2.099 euros per liter, you can follow these steps in ordere to calculate the price of the gasoline in US dollars per gallon:

1. Convert 2.099 euros to US dollars:

(2.099\ euros)(\frac{1\ US\ dollar}{0.7564\ euros})=2.774\ US\ dollars

Then, the price in US dollars per liter is 2.774\ US\ dollars\ per\ liter

3. Knowing that:

1\ liter=1.0567\ quarts\\\\4\ quarts = 1\ gallon

You can make the conversion from 1.0567 quarts to gallons:

(1.0567\ quarts)(\frac{1\ gallon}{4\ quarts})=0.2641\ gallons

4. Set up the following proportion:

\frac{2.774}{0.2641}=\frac{x}{1}

Where "x" is the the price in US dollars per gallon.

5. Solving for "x", you get:

\frac{(2.774)(1)}{(0.2641)}=x\\\\x=10.503
