Itd 5 Brad took four boxes of chocolates into work.
There were 12 chocolates in each box.
At the end of the day only five chocolates had not been eaten.
Write the number of boxes of chocolates that were eaten as:
a a mixed number
b an improper fraction.

a. 3 7/12; b. 43/12

Step-by-step explanation:

4 - 5/12

48/12 - 5/12

43/12 chocolates were eaten

3 7/12

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
