theres only one "a" in this array. we are trying to find the ways to write arch not array. in arch there is only one a, so only one way to use a. i don't really get your solution either bc there are many ways to go to h....
thank you you too! :))
Adding 3a+mb to both sides of the second equation, we have 3a+2b=2 9a+(m+2)b=k We multiply the first equation by 3, in order to make the coefficient of a equal to 9: 9a+6b=6 9a+(m+b)b=k This system will have infinitely many solutions when both equations are the same. This occurs when k=6 and m+2=6.... im sure you can figure out what m is :)))
i uh had a brain fart
wait nvm i got it. the 2nd equation is simplified to x^12 and since x^6 = 8, then x^12 = 8x8 = 64...
not sure if there is tax or not, but there are two ways you could do this.
#1
$48 x 0.25 = how much discount.
$48 - how much discount = total
#2
$48 x 0.75 (100%-25%) = total.
Either way, you should get the same answer...
you can find the answer by introducing a variable to help find the percent you are trying to find (people who oonly bring an umbrella) also draw a venn diagram and see if it helps.
I also believe that there was already a post like this several years ago...
make sure that you dont mix up the students that bring both...
(if you would like to check your answer, I got 64%)
so like theres 5 vowels, and then the other 2 letters can be from the 26 letters of the alphabet... right?
I'm not sure if I'm correct because im not very good at math. But:
12 (1+2 = 3), 21 (2+1 = 3), 111 (1+1+1)... 3
not sure lmao
