Let the number be x, then:-
3x + 12 - 5x = 22
-2x = 10
x = -5
To convert
to a percent, you must convert it to a decimal first
Divide the numerator(top) by the denominator(bottom)
5÷20=.25
All percents are based off of "100%" so multiply .25 by 100(%) which is 25%
Answer: 25%
I think it's 1/6. Because before school she drinks 1/4 then before lunch she drink 2/3 if 1/4 so you would multiply. 1*2=2. 4*3=12. So you get 2/12 or if you simplify, 1/6
I think it’s 4x^2 - 33x + 5/ x if I looked at your question correctly
