Can anyone help with this?

1. 8 seconds

2. 15 quarts

Step-by-step explanation:

1. You can use proportions. You first put 9 quarts over 6 seconds equals to 12 quarts over x. Cross multiply and you will get 8.

2. You can also use proportions. Still put 9 quarts over 6 seconds equals to x over 10 seconds. Cross multiply again and you will get 15 quarts.

the correct answer is 5

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
