Answer:

The value of bc is 5.9 units.

Step-by-step explanation:

Given information: b is between a and c, ac=15.8 and ab=9.9.

We need to find the measure of bc.

Since b is between a and c, therefore the segment ac is the sum of two segments ab and bc.

$ac=ab+bc$

Substitute ac=15.8 and ab=9.9 in the above equation.

$15.8=9.9+bc$

Subtract 9.9 from both sides.

$15.8-9.9=9.9+bc-9.9$

$5.9=bc$

Therefore the value of bc is 5.9 units.

Answer:

15 days

Step-by-step explanation:

You have 5 cups of food, and you give him 1/3 a day.

So, <em>5 divided by 1/3</em>, which would get you 15 days. Or you could cross-multiply, meaning you multiply across, but in this case I just made them line up so you can see how to do it. $(food)/(cupsperday) = 5/\frac{1}{3} \\OR\\\frac{(food)}{1}*(cupsperday) = \frac{5}{1} *\frac{3}{1}$
