For question 13 ( operations ) you must do the brackets first, so you do 5+1 first which equals __ and then you divide the answer by 6.
I hope this helps you
h=S-2pi.r^2/2pi.r
Use distributive property.
4(m - 2) = 24
Add 8 on both sides to leave the variable on one side.
4m - 8 = 24
+8 +8
Divide 4 on both sides.
4m = 32
---- ------
4 4
You'll get a solution of 8.
m = 8
Check:
4(8 - 2) = 24
32 - 8 = 24
24 = 24

Step-by-step explanation:
Since the student answered 80% of the questions correctly, we can find 80% of 20 to answer this question.
[] First we will convert the percent into a decimal format;
80% / 100 = 0.8
[] Then we will multiply this by 20 to find our answer;
20 * 0.8 = 16 questions answered correctly
