User: Which property is illustrated by 6 x 5 = 5 x 6?

Weegy: The property is illustrated by 6 x 5 = 5 x 6 is commutative. In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. [ It is a fundamental property of many binary operations, and many mathematical proofs depend on it.
x*y=y*x

User: Solve the inequality. Show your work.
|r + 3| 7

Weegy: for values of r + 3 ? 7, |r+3| = r+3
for values of r + 3 < 7, |r+3| = -(r+3) = -r-3
so for values of r ? 4, solve for r + 3 ? 7
so r ? 4. [ That is all values greater than equal to 4
for values of r < 4, solve for - r - 3 ? 7
-r ? 10
r ? -10
so all values less than or equal to -10
so to sum it up, the answer is r ? -10, and r ? 4 ] majasalv17|Points 110|
