Answer:
7/165
Step-by-step explanation:
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242
I think this is what you do. Hope it helps!
Add these together.
You get -15y=-45
So y=3
Now plug in to first equation.
8x-8(3)=-16
8x-24=-16
8x=8 so x=1
Check both values in second equation.
-8(1)-7(3)=
-8-21=-29
It works...so x=1, y=3
Answer:
multiply them like you normally would and add up the decimal places, then place ur decimal.
Step-by-step explanation:
2 1/7 X 3 2/3
first change into improper fraction
15/7 X 11/3
you can divide the 15 and 3 by 3 so it would be
5/7 X 11/1
and you get 55/7 or 7 6/7
Put all the numbers in order, then it comes down to 11 and 9 divide by two and add. The answer is 10.
