If you know the 7x8=56 how can you use the Commutative Property of Multiplication to find the product of 8x7?
boyakko [2]

Answer:

The communicative property for multiplication states that the order of the multiplicands and can be swapped and the resulting product stays the same.

So

A * B = B * A

So if

7*8=56

then the commutative property says

8*7=56 as well since you can swap the order of the terms on the left and not change the result.

This property is true for addition and multiplication. It does not hold for subtraction or division.

Hope that makes sense and helps. (:

What is the value of X?
alexandr402 [8]

Answer:

x = 45

Step-by-step explanation:

The 3 angles of a triangle add up to 180

<a + <b + <c = 180

substitute what you know

55+ 80 + <c = 180

combine like terms

135 + <c = 180

subtract 135 from each side

<c = 180 -135

<c = 45

x = 45
