Answer:
The correct option is the second option;
a. Division property of equality
b. Symmetric property of congruency
c. Multiplication property of equality
Step-by-step explanation:
a. For the equation in part a., we have;
6·a = 30
Therefore;
6·a/6 = 30/6
a = 5
Which is of the form, if a = b then a ÷ c = b ÷ c, which is the division property of equality
b. For the relationship in part b., we have;
∠ABC ≅ ∠LMN
∠LMN ≅ ∠ABC
The above relationship is of the form, if a ≅ b then b ≅ a, which is the symmetric property of congruency
c. For the equation in part c., we have;
Multiply both sides by 3, to get;
Cancel like terms on the left hand side of the equation, to get;
2·(x - 6) = 24
Which is of the form, if a = c, then a × c = b × c which is the multiplication property of equality
The cost price of each pair of socks is 3 dollars and 97 cents
The total money paid by Jessica for 4 pair of socks = $20
The money that the cashier returned = $4.12
It is also given that, each pair of sock would cost same price
We need to find, The cost price of each pair of socks
To do that, first let's find
The amount that was paid for 4 pair of socks = 20 - 4.12 = $15.88
Now,
The cost price of one pair of sock = 
= $3.97
= 3 dollars and 97 cents

It would be 5 months until the price for the notebook computer would be the same. Here are the steps to solving the problem:
1. Step up the equation, 200 + 10x = 100 + 30x
2. Subtract 100 from both sides and Subtract 10 from both sides,
100 - 200 = 10x + 30x, 100 = 20x
3. Solve for x, 100/20 = 20x/20, x= 5
