Pi is an irrational number and the ratio of a circle's circumference to its diameter.
If 1% as a fraction is 1/1 then half of 1 (0.5), as a fraction should be 0.5/1
Answer:
Step-by-step explanation:
4.2x+4.7=18.6
Multiple each term by 10
42x + 47 = 186
Collecting like terms
42x = 186 - 47
42x = 139
x = 139/42
x = 3 13/42 or 3.3
16/c =8
That means 16 divided by same random number "c" makes the number 8. This also means that 8 times that random number you divided by makes 16.
Using this, you can rearrange the equation in various ways.
16/c =8
16 = c*8
c = 16/8
We only really need that last one, c = 16/8,
16/8 = 2
c = 2
