PEMDAS
When solving an equation we do them in reverse order
AS adding and subtracting
MD multiplication and division
E exponents
Basically we are trying to get the variable alone.
12=10-3x
subtract 10 from each side
then divide by -3 on each side
3/5 x -12 = 18
first add 12 to each side
then multiply by 5/3 to each side
Radius = 50.93
Diameter = 101.86
Area = 8148.87
You add all of them up and then do decided by 10 because there are 10 number in there it’s 10.1
Set up a proportion:
=
To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100
