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>
Consider re-writing this formula as "A = pi*r^2." The backslash symbol "\" is unnecessary.
If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:
A/pi = r^2
Taking the square root of both sides, sqrt(A/pi) = r (r must be positive in this situation).
Answer:
the answer is y=3x+9 if you are looking for it to be in slope intercept form
Answer:
1/3 if it's a standard die with the highest number being 6.
Step-by-step explanation:
Answer:
A) buddy = sadie + 14
B) buddy + sadie = 136
A) buddy -sadie = 14
Adding equations A & B
2 * buddy = 150
buddy = 75 pounds
sadie = 61 pounds
