Total of all frequencies:
5+8+1213+11= 49
Divide the frequency of 59-61 by total frequencies:
13/49 = 0.265 which rounds to 0.27
The answer is 0.27
When u all those 5 numbers together u get 354 so:

3x+4=10
Subtract 4 from both sides
3x=6
Divide both sides by 3
X=2
Sides = 10,10,5
Problem 5. 4x+1=29
Subtract 1 from both sides
4x=28
X=7
