From this, we can see that the total amount of students being asked = 12 + 8 + 6 + 4 = 30.
12 of 30 like rock, in percentages that is 12/30 = 40$
Full circle has 360 degrees.
40% * 360 degrees = 144 degrees
144 degrees should represent rock music on a pie chart.
Hope this helps!
Simplifying
n + -16 = m
Reorder the terms:
-16 + n = m
Solving
-16 + n = m
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + n = 16 + m
Combine like terms: -16 + 16 = 0
0 + n = 16 + m
n = 16 + m
Simplifying
n = 16 + m
The GCF is 36 since 36 can go into 144 (:
