Let x = amount of appliances Jack sold

Let y = amount of appliances Dion sold.

We need to construct a system of equations to solve this problem

33 = x + y

y = 2x - 3.

Let's solve this system of equations by substitution.

33 = x + (2x - 3). Combine like terms.

33 = 3x - 3. Add 3 to both sides.

36 = 3x. Divide both sides by 3

12 = x. Plug this value into one of our original equations.

33 = 12 + y.  Subtract 12 from both sides

y = 21

Jack sold 12 appliances and Dion sold 21 appliances.

Suppose you know the slope of a linear relationship and one of the points that it's graphed passes through. How can you determin
liberstina [14]

If you know the slope of a linear relationship as well as one of the points, you can determine if the relationship is proportional if the value of y is equal to the value of the slope times the x value.

<h3>When is a relationship proportional?</h3>

The linear relationship of x and y is said to be proportional if:

y = slope × x

This means that the value of y is directly related to the value of x such that when x is increased by a certain value, you get y.

If this condition is not satisfied then the relationship is not proportional.

The linear relationship above is therefore proportional if the value of y in the point is the same as x when multiplied by the slope.

grigory [225]

Answer:

25%

Step-by-step explanation:

Given parameters:

Amount earned by Jessica per month = 800

Total savings target per year  = 2400

Unknown:

Percentage of savings = ?

Solution:

The total earning per year will be the amount earned per month multiplied by the total number months;

 Amount earned in a year = 12 x 800  = 9600

Let the percentage of savings per year  = y%

  Now;

              2400 = \frac{y}{100} x 9600

                  y = 25%

Hey there!

To figure out what "x" means, you can divide the numbers 126 and 14  . . .

126 divided by 14 = 9

9 x 14 = 126

9 = x

----------------
x = 9
----------------

Hope this helps you.
Have a great day!
