Para la ecuación 2x+5y-3=0, halla la coordenada que falta (-

Step-by-step explanation:

We have the equation .

The ordered pairs of this equation have the form

Where x is the independent variable and y is the dependent variabe.

That is, the points belonging to the line have the form

For .

So, we need to find for x_0 = -3.

Then we substitute x = -3 into the equation and clear the value of y.

.

Then the ordered pair is:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
