Georgia is making sock puppets. each pair of socks costs $2. georgia bought 6 pairs of socks. how much did she spend?

$12

Step-by-step explanation:

First you would have to write down the number of socks.  That is 6.  That means 6 is the first part of our equation.  Then, we have to multiply this by the $2.  You have to do this because this is how much each pair costs.  Then you would do 2 times 6 equals 12.

If each pair of sock is 2$

and she bought 6

multiply 2 by 6

explanation

2x6 = 12

because a pair of docks is two so multiply by how much pairs she bought

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
