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. (:

Answer:
15 years old.
Step-by-step explanation:
Let Jim's age now be one unit (1u).
His uncle's age now is then 4 units.
Jim's age in 10 years = 1u + 10
Jim's uncle's age in 10 years = 4u + 10
In 10 years, Jim's uncle's age will be 20 years more than twice Jim's age.
Twice Jim's age =

Since Jim's uncle's age is 20 years more than this, we can say that his uncle's age is equal to

which is equal to

We found out that Jim's uncle's age in 10 years is 4u+10. Hence

We subtract 10 from both sides:

Therefore

and one unit is 15. Hence, Jim's age now is 15.
