Answer:
y = x - 8
Step-by-step explanation:
There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!
Looking at inputs 20 and 21, the outputs are 8 less than the inputs. Check the other inputs and notice that the same pattern holds up.
Negative reciprocals of each other
Answer:
see below
Step-by-step explanation:
yes it matters, if you don't know how to write a repeating decimal as a fraction you can use this trick
let's say we don't know what it is
0.33333333...
so we see that there's only one repeating digit
so the answer is
(the repeating digit)/(9)=3/9
and that simplyfies to 1/3
let's try another one
0.67676767...
as you can see know the repeating is 67
so the answer is
(the thing that repeats)/(99)=67/99
do you see a pattern?
when we have a number x of repeating decimals
the denominator of the fraction (the thing that's down) is 9999..99 in there must be x 9's
let me explain
if you have 3 repeating decimals
the denominator will be 999
you see 3 nines
and so on.
Answer:
in the fraction 5/3 you can simplify it to be 1 2/3 and if you dont identify the whole in the mixed fraction 1 2/3 then you will get the fraction 2/3
