Remember
so
notice that 200=2*2*2*5*5, so x cannot be a whole number
take the log base 10 of both sides
divide both sides by
if we used
instead of
we would get
because
Answer:
(y-5t)/5=x
Step-by-step explanation:
y=5t+5x
factorize
y=5(t+x)
divide both sides by 5
y/5=5(t+x)/5
y/5=t+x
make x to stand alone
y/5-t=x
take lcm of 5 and 1
y/5-5t/5
y-5t/5=x

Look at it this way:
When you flip a coin, the probability of it landing with EITHER side showing
is 100%.
This leads us to the rule ...
The sum of the probabilities of
all possible outcomes is 100%.
For a coin: (probability of heads) plus (probability of tails) = 100%.
That just says: We're 100% sure that the coin will land with either
heads or tails up.
An "honest" coin gets heads 50% of the time and tails the other 50%.
But if the coin is all bent and squashed and has a feather stuck to
one side and a wad of gum on the other side so that it comes up
heads 70% of the time, then the coin isn't 'honest'. But it still has to
land EITHER heads OR tails, so the sum of the probabilities is still 100%.
So the probability of heads is 30%.
