Answer:
<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>
Step-by-step explanation:
<u>Length, Area, and Volume Scale Factors</u>
If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is
and the scale factor of their volumes is
.
We are given the scale factor of the surface areas of two similar containers A and B as 4:25.
The length scale factor is

The volume scale factor is:
= 125:8 = 15.625
Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.
Thus, after she pours the 15th container, in the middle of the next one, the work will be done
You need to know:

Be careful though:

Using this principle, we can say:
12 1/3 = 37/3
3 2/3 = 11/3
Quantity of juice left = Initial quantity - Quantity drunk
So:
Quantity of juice left = 37/3 - 11/3 = 26/3
There will be 26/3 ounces of juice remaining after 3 2/3 are drunk from the total of 12 1/3 ounces that Deacon had initially.
You just add them :)
2x+7x+3y-3y=-5+9
3y and -3y is 0 which means this equals to 9x=4, so B
