The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols
<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.
The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:
</span>
Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>
10 because 30 divided by 10 equals 3 and 50 divided by 10 equals 5 and 3 and 5 only have a GCF of 1 so 10 is your answer

Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Step-by-step explanation:
We can represent this using two equations:
- Variable <em>x </em>represents cups of coffee, and variable <em>y</em> represents bottles of water.
5<em>x</em> + 2<em>y</em> = 12
4<em>x</em> + 7<em>y</em> = 15
Your answer for the value of <em>x</em> and <em>y</em> should be
<em>x</em> = 2
<em>y</em> = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.
