Answer: x = 13 and y = 8
Step-by-step explanation:
Two numbers must add to 21. We don't know them yet, so let's just use a placeholder for both of them for now.
x + y = 21
Their difference is five, meaning that if we subtract one from the other, we get five. Again, we don't know the numbers yet, so we'll add a placeholder for now.
x - y = 5
We can now solve a system of equations for x.
x = y + 5
y + 5 + y = 21
2y + 5 = 21
2y = 16
y = 8
x - 8 = 5
x = 13
So x = 13 and y = 8
Answer:
-9, 1/5, 12/20
Step-by-step explanation:
-9 is negative so it will always be the least. It helps to turn the fractions into decimals. To do this, you can just divide 1 by 5 and 12 by 20.
1/5 = .2
12/20 = .6
So, 1/5 is less than 12/20.
This makes the order -9, 1/5, 12/20.
If you mean classifying numbers, then I think -35.64 will be a real, rational number
Rational numbers are written as decimals or factions
If a number has a decimal or faction, the number can not be a integer. If its not a integer, then it cannot be a whole number.
