Division CANNOT be commutative, here is why
lets say the problem is 24÷4
it is obviously 6
but when you flip 24÷4, you get 4÷24
and... 4÷24 is 0.16666666
6 and 0.1666 is totally different :p
Answer:
if its 16 then its 24
Step-by-step explanation:
A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.
B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.
how many months for the cost to be the same?
![\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4](https://tex.z-dn.net/?f=%5Cstackrel%7BA%7D%7B12%2B28m%7D%3D%5Cstackrel%7BB%7D%7B20%2B26m%7D%5Cimplies%2012%2B2m%3D20%5Cimplies%202m%3D8%5Cimplies%20m%3D%5Ccfrac%7B8%7D%7B2%7D%5Cimplies%20m%3D4)
well, since the cost for both is the same, we can just get A's, knowing that B is the same
![12+28(4)\implies 12+112\implies 124](https://tex.z-dn.net/?f=12%2B28%284%29%5Cimplies%2012%2B112%5Cimplies%20124)
Answer:
x= 0.78 (rounded to the hundredth)
Step-by-step explanation:
-5.5x + 0.46 = -3.94
You need to isolate x so the easiest thing to do is subtract 0.46 and move it to the other side of the equal sign.
-5.5x= -3.84 - 0.46
-5.5x = -4.3
divide -5.5 to get x alone
x= -4.3/-5.5
x= 0.78
