There is no distinct question here so no one is going to be able to answer. :(
There is no question here :/
Plus the wording is confusing.
Hi Mellie
I can't find your invisable post.
How long ago did you post it?
Maybe you should just post it again ://
after running one quarter of a race, wally had to slow down. he ran another fifth of it, and he had to walk the rest of the way. what fraction of the race did wally walk?
\(1-(\frac{1}{4}+\frac{1}{5})\\ =1-(\frac{5}{20}+\frac{4}{20})\\ =1-\frac{9}{20}\\ =\frac{11}{20}\\\)
what is the answer of this q
B= -11/2
C= -5 1/3
\(BC=-1\frac{1}{2}\times -5\frac{1}{3}\\ \mbox{A negative times a negative = a positive}\\ BC=\frac{2+1}{2}\times \frac{15+1}{3}\\ BC=\frac{\not{3}}{2}\times \frac{16}{\not{3}}\\ BC= \frac{16}{2}\\ BC=8\)
how can i get to the number 12 with decimals in two ways?
0.5*24=12
11.6+0.4=12
I have no idea what you are talking about
(3x2 - x2) + (4x3) + (2 - 7)
\((3x^2 - x^2) + (4x^3) + (2 - 7)\\ =3x^2 - x^2 + 4x^3 + 2 - 7\\ =2x^2 + 4x^3 -5\\ = 4x^3+2x^2 -5\\ \)
inverse sine is the same as arc sine. So use [2nd] [asin]
2/y^2 +9/y-7=0
You are lucky to get any help with that opener!
I'd multiply through by y^2 but you need to note that y cannot =0
\(2+9y-7y^2=0\\ 7y^2-9y-2=0 \)
Now just use the quadratic formula :)
