You do IXL too?

-3(n+5)=12 n must be -9 because -9+5=-4 then -4*-3=12

19.625= 19 and 5/8

First get a common denominator 2/3 becomes 16/24 then 6/8 becomes 18/24 so 

16/24+18/24=34/24 or 1 10/24 or 1 5/12

well to get that you do 2755/14 = 196.7857142857142857

 well since you can't have a .7857142857142857 of a person you round up to 197 so about 197 people visited the store each day

So first get these to a common denominator so now it's 8/20 (2/5) 2/20(1/10) 3/20

so in order it's: 2/20  3/20 8/20

Do you seriuosly want to know?

(Will I get in trouble for talking about this Melody? Assuming they are talking about the drug.)

(5.8*10^7)+(8.237*10^8)=881700000 in scientific notation that would be 8.817*10^8

assuming you mean 10*5.555^12 then it goes like this

5.555^12 = 863393469.2787279401418596

big decimal there!

then you do 

863393469.2787279401418596*10 = 8633934692.787279401418596

or you can do this=

10*5.555 = 55.55

then

55.55^12 = 863393469278727940141.8595872158940237

x- 1 1/3=2 2/9 so first lets get them to a common factor so 1 1/3 becomes 1 3/9 then you add 2 2/9 +1 3/9=3 5/9 so x= 3 5/9
