4n-40=7(-2n+2)

4n-40=-14n+14

subtract -4n from both sides

-40 = -18n +14

subtract -14 from both sides

-54=-18n

divide both sides by -18

3 = n

12.<br>The container shown has a capacity of 60 milliliters.<br>What fraction of it is empty?<br>

White raven [17]

This is an incomplete question, the image is shown below.

Answer : The fraction empty container is, $\frac{7}{12}$

Step-by-step explanation :

As we are given that:

The capacity of container = 60 mL

In the given figure, the container is filled with 25 mL.

That means,

60 - 25 = 35 mL container is empty.

Now we have to calculate the fraction of it is empty.

The fraction of it is empty = $\frac{\text{Capacity of empty container}}{\text{Total capacity of container}}$

The fraction of it is empty = $\frac{35mL}{60mL}$

The fraction of it is empty = $\frac{7}{12}$

Therefore, the fraction empty container is, $\frac{7}{12}$

10. Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 3 liters of natural oil for every 4

jeyben [28]

you have the ratio of natural:synthetic so;

3:4

3+4=7

357/7=51

3*51:4°51

153:204

therefore, it'd be 204 litres of synthetic oil!!

i hope this helps you!!

The slope of the line is “rise over run.” That’s the vertical change between the two points (the difference in the y-coordinates) divided by the horizontal change over the same segment (the difference in the x-coordinates).
