Answer:
L=15 6/8feet
B=20 feet
Step-by-step explanation:
The difference is
We must find the common denominator of the fractions.
The common denominator of and is ; therefore we have
now it is easy to subtract using the number line: we have to move units to the left in order to get to .
Thus our answer is
5/8
The sectors are labeled 1,2,3,4,5,6,7,8
Numbers less than 4: 1,2,3
Multiples of 4: 4,8
We are looking for 1,2,3,4,8 = 5 choices
P (1,2,3,4,8) = Number of choices/ total
= 5/8
w=15
-24=-3w+21
We move all terms to the left:
-24-(-3w+21)=0
We get rid of parentheses
3w-21-24=0
We add all the numbers together, and all the variables
3w-45=0
We move all terms containing w to the left, all other terms to the right
3w=45
w=45/3
