Answer:
A. 11•(8 + 7)
B. 8•(11)-7•(11)
C. 11•(7) + 11•(8)
Step-by-step explanation:
The commutative property of multiplication lets you swap the order of the factors in the product:
(8 +7)•11 = 11•(8 +7)
The distributive property lets you eliminate parentheses:
(8 +7)•11 = 8•11 +7•11
And the commutative properties of addition and multiplication let you rearrange this sum of products to ...
(8 +7)•11 = 11•7 +11•8

18 = 10 + 2k
move 10 to the other side
sign changes from +10 to -10
18-10=10-10+2k
18-10= 2k
8= 2k
divide by 2 to get k by itself
8/2= 2k/2
Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k
k=8/2
Answer: k= 4
