Answer: the solutions are (2, 5)

Step-by-step explanation:

The given system of simultaneous equations is

5x – 4y = -10 - - - - - - - - - - - 1

3x + 2y = 16 - - - - - - - - - - -2

We would eliminate x by multiplying equation 1 by 3 and equation 2 by 5. It becomes

15x - 12y = - 30

15x + 10y = 80

Subtracting, it becomes

- 22y = - 110

Dividing the left hand side and right hand side of the equation by - 22, it becomes

- 22y/-22 = - 110/-22

y = 5

Substituting y = 5 into equation 1, it becomes

5x – 4 × 5 = -10

5x - 20 = - 10

5x = - 10 + 20

5x = 10

x = 10/5 = 2

A certain factory produces and sells 8000 cars per month, making a monthly net profit of P dollars. They sell
vredina [299]

Answer:

p= 8000n-8000c

Step-by-step explanation:

8000

p= n - c

or

p= 8000n-8000c

Esentially you need to subtract n, the amount they sell each car for by c, the amount it costs to produce a car, <em>(which should be less because the company has to make money)</em><em> </em>this would give you the total they make a month, P.

Because the amount of cars is constant, 8000, you can always multiply the cost of the car and how much its sold for by 8000. Otherwise, you would have another variable like k, which would be how many cars sold

Actual distance between two places is 130 miles. The scale of the map is
Lynna [10]

Answer:

1.3 inches

Step-by-step explanation:

1. Determine what you already know in order to set up the equation:

1 inch = 100 miles

<em>x</em> inches = 130 miles

Solving for <em>x</em>

2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)

\frac{100}{1} = \frac{130}{x}

3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)

100<em>x</em> = 130

4. Divide each side by 100 to isolate the variable.

<em>x</em> = 1.3
