Step-by-step explanation:
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5
Check answers. (Plug them in to make sure they work.)
b=5 (Works in the original equation)
Answer:
b=5

Step-by-step explanation:
All you have to do is turn the picture upside down, revealing a bunch of numbers in a row.
64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.
