Two numbers have an average of 18, and a difference of 10. Form two equations and solve them to find these
Troyanec [42]
Answer: x = 23 and y = 13

Explanation:

let x and y be the two number.

Where:

(x + y)/2 = 18 => x + y = 18 x 2 = 36

and:

x - y = 10

Thus we get:

x + y = 36 (1)
x - y = 10 (2)

Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23

If x = 23

then x - y = 10
23 - y = 10
-y = -13
y = 13

Como puedo poner 2 3/5 en decimal​
Alex73 [517]

When turning a fraction into a decimal, any whole numbers comes before the "." and the fraction will become after the ".".

To make it simple, turn the fraction into a "over 100" fraction to make it easier.

Multiple both numeriator and denominator by a specific number, to turn the denominator into a 100. You must times the numeriator as well since your changing the denominator.

100 / 5 = 20

So now, multiple both sides of the fraction by 20.

3 x 20 = 60

5 x 20 = 100

2 60/100

Now, put the whole number in front of the decimal symbol.

2.___

Now, take the numeriator and put it behind the decimal symbol.

2.60

So, when turning 2 3/5 into a decimal, it is 2.60.

You are to demonstrate that you understand what represents a function and what does not represent a function. You may do this by
My name is Ann [436]

We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.

For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.

We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
