Answer:
The answer to quetion 14 is A.
The answer to quetion 15 is B.
Step-by-step explanation:
For quetion 14, you must use the formula pemdas.
Solve the parenthesis first for p, the exponents next for e, multiplication and division for m and d, addition and subtraction for a and s. First you solve whats under the parenthesis. In this case there are no exponents so we would solve the multiplication and divison under the parenthesis.
3 x 2 = 6
8 ÷ 2 = 4
Now our equation looks like this:
4 ( 12 - 6 + 4 )
12 - 6 = 6
6 + 4 = 10. Now we must multiply it by 4.
10 x 4 = 40.
Explanation for quetion 15:
1/5 of 30 = 6 because 6 x 5 = 30
1/3 of 30 = 10 because 10 x 3 = 30
6 + 10 = 16
That leaves the remaining students ( 14 ) to chose station M.
