Answer:
x=-17,y=3
Step-by-step explanation:
x+y=-14
x=x
y=x+20
x+(x+20)=-14
2x+20=-14
2x=-14-20
2x=-34
x=-34/2
x=-17
y=-17+20

Answer:
Step-by-step explanation:
It can be useful to consider the percent symbol (%) as a shorthand way to write /100. That is, where you see %, /100 is completely equivalent.
49% = 49/100
If you recognize that 1/100 (one hundredth) is 0.01 in decimal (one hundredth), then you can see that 49/100 = 49×0.01 = 0.49.
__
A lot of folks consider the % symbol to be separate from the number, just as units of degrees or hours or inches might be. So, they tell you to do the conversion by moving the decimal point on the % value 2 places to the left (and drop the % symbol):
49% = 49.% = .49
_____
<em>Additional comment</em>
As you can tell, I think of the % symbol as part of the number 49%, just as /100 is part of the number 49/100. Forty-nine hundredths can be written as any of 49/100 or 0.49 or 49%.
