Answer:
15.7
Step-by-step explanation:
The equation for finding the circumference of a circle is
2 x pi x r(radius). Radius is half the diameter.
5/2=2.5
2 x 3.14 x 2.5
=15.7
6m+1=-23. Do the inverse operation of adding 1 which is to subtract 1 to both sides =====> 6m+1-1= -23-1
You divide by 6 both sides
6m/6=-24/6
m= -4

Answer:
Value of stamp collection = (45b + 43) cents
Step-by-step explanation:
What we have here is as follows;
if there are x 3-cent stamps, then there are 4x 10-cent stamps
So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps
Number of 2 cents stamps = b
This means that x-1 = b
Thus, x = b + 1
So the value of the stamp collection is as follows;
x 3 cents stamps = 3(b+ 1) = 3b + 3 cents
4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40
value of the 2 cents stamp = 2b cents
Total value is thus;
2b + 40b + 40 + 3b + 3 = (45b + 43) cents
Answer: 
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:
a=1 b=-3 c=8
Inserting a b c values into formula: 
Simplifying: 
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
