The expression 12x+15x-11x can be combined because of which property a. commutative property of addition b. distributive property c. additive inverse property d. multiplicative property

Option A.

Step-by-step explanation:

Commutative property of addition says that if we add two or many numbers, order doesn't matter.

Let there are three numbers a, b, and c.

When we add them by commutative property, result will remain same.

If we add [(a + b)+ c] or [a + (b + c)], result will be same.

Therefore, 12x + 15x - 11x = (12 + 15 - 11)x

                                         = (27 - 11)x

                                         = 16x

Option A. Commutative property will be the answer.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
