Meg bought 20 pairs of socks. Each pair cost $3. How much did she pay?

$60

Step-by-step explanation:

Since 1 pair cost $3

20 pairs of socks would cost Z (let the unknown cost be Z)

i.e 1 pair = $3

20 pairs = $Z

To get the value of Z, cross multiply

Z x 1 = 20 x $3

Z = $60

Thus, Meg bought the 20 pairs of socks for $60

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
