Remember you can do anything to an equation as long as you do it to both sides (except divide by 0)
add like terms
3x-x=3x-1x=2x
so
3x-x+2=12
2x+2=12
subtract 2 from both sides
2x=10
divide both sides by 2
x=5
If 63 cand are 21% we must find out what 1% is
To do that we must divide 63 by 21
63/21 = 3
So 1%=3 cans
To find out what a percentage equals we must times it by 3
46 * 3 =138 cans
33*3 = 99 cans
Hope this helps :)
Answer:
~ 2.3%
Step-by-step explanation:
A percentage is a amount divided by the total.
2/85 (2 is the amount decreased) 0.02352941176470588235294117647059
That makes around 0.023.
That multiplied by 100 is 2.3 and that makes the percentage.
So yeah.
