Hello!
First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.
34/3≈11.33333333
By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.
I hope this helps!
Y= 8/2x + -4 i think is that one
Sum means add
x and y are the numbers
sum i 44
x+y=44
smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y
substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32
the numbers are 12 and 32
Whoever worded this question made it confusing, 87.5%?
