Answer:
A. Subtraction Property of Equality
Step-by-step explanation:
3x + 4 = 10
Subtract 4 from both sides ---->Subtraction Property of Equality
3x + 4 - 4 = 10 - 4
3x = 6
So
If 3x + 4 = 10, then 3x = 6
Answer
A. Subtraction Property of Equality
√45 = √9√5 = 3√5
√20 = √4√5 = 2√5
3√5+2√5-√5=4√5
answer = 4√5

The fraction of a circle represented by the shaded region is:
S '/ S = ((8/5) * pi * r) / (2 * pi * r)
Rewriting we have:
S '/ S = ((8/5)) / (2)
S '/ S = 8/10
S '/ S = 4/5
Then, we can make the following rule of three:
(64/5) pi -------> 4/5
x ----------------> 1
Clearing x we have:
x = ((1) / (4/5)) * ((64/5) pi)
Rewriting:
x = (5/4) * ((64/5) pi)
x = (5/4) * ((64/5) pi)
x = 50.24
Answer:
The area of the complete circle is:
x = 50.24
Answer:
C) 
Step-by-step explanation:
The formula for area is
A=pi * radius ^2
If the diameter is 40, the radius is 20
Therefore
