PLZZ HELPP!! Water is poured from a 1.5 L water bottle into an empty glass until both the glass and the bottle are 3/4 full. Wha
Natalka [10]

Answer:

0.5 L

Step-by-step explanation:

volume of bottle: 1.5 L

amount of water = 1.5 L

volume of glass: x

3/4 full is the same as 0.75 full

vol of water in bottle + vol of water in glass = total vol of water

      0.75(bottle)          +       0.75(glass)          =           1.5

0.75(1.5) + 0.75x = 1.5

0.75x = 0.375

x = 0.5

4 + (x + y) = (4 + x) + y
Bezzdna [24]

The property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.

<h3>What is the number?</h3>

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

4 + (x + y) = (4 + x) + y

As we know,

Commutative property is the property in which we can arrange the terms withouth changing the sign.

For an example:

a + b = b + c

In the given expression

4 + (x + y) = (4 + x) + y

The Commutative property is applied to rearrange the terms.

Thus, the property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.
