Answer:
11
Step-by-step explanation:
30-2(7+2)-1
PEMDAS says parentheses first
30-2(9)-1
Then multiply
30 -18 -1
Then subtract
12-1

this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
You divide circumference by 3.14 to find the diameter
Divide the diameter by 2 to get the radius
Use the formula for area with the radius that you just found and you should get your answer
