I don't think he left
He left me
I am eating ice cream
Does anyone know when the best time to use substitution method is
?
to solve systems
of equations
when u plug and chug^
idk otherwise
i only pass math cause I make friends with my math teachers. :/
LOL
it would be best if the values are convenient. If it’s y = than for sure
I do over use the elimination when I could’ve done substation a lot
It all depends on how easy it is to isolate the variable. If you isolate a variable but you hav e fractions, it’s better to use elimination instead
such as 5y + 4x = 5. If you isolate a variable you get a fraction which is pretty annoying
Do y’all think this is an acceptable statistics example
Ex 2 is pretty repetative
That is unless you need to follow a format with key words
Ex.2 is more or less just to give my class a migraine
Communications
Oh I haven’t taken that class
I can't see because of the glare, sorry
it seems like it would be a linear equation with 2 variables and you have to isolate a variable than solve for the other one
wait
well there's 3 variables but
i’ll take a better picture
or wait, he grabs the same amount every day so you would only need 1 variable
is that better
yeah, I'll try to solve it although idk how to since I didn't do this in a while
or at least help
thank you
i’ve been trying for 20 minutes
at the minimum he would have to put 30 g worth of coins if you add up the weight of 10,50, and 20 cent coins
yeah i got that part
it’s just finding the combinations equal to 1000
but there’s only 30 possible combinations
we could try prime factorization
