Answer:

  Tina is 12 and MIna is 15

Step-by-step explanation:

Age problems can often be worked by backing out any of the changes in age so as to match the conditions specified at a given time.

Here, the ratio is given for now. The sum of the two ages is 6 years less now than it will be after 3 years, so is now 33 -6 = 27.

The sum of ratio units now is 4+5 = 9, so each ratio unit stands for 27/9 = 3 years of age. The ratio of current ages is ...

  3×4 : 3×5 = 12 : 15

Tina is 12 and MIna is 15.

_____

<em>Check</em>

After 3 years, their ages will be 15 and 18, which will total 33.

3x^2-192=0
3x^2=192
x^2=\frac{192}{3}
x=\pm \sqrt{64}
x=\pm 8

x=-8 and x=8 are the solutions

liraira [26]
You should purchase 322 boxes. If you take 7.714 decided by 24 solar panels per box, you get 321.416667 and because you can purchase .416667 of a box, you round up to 322
