Sadie practiced her spelling words for 3/4 of an hour, and Max practiced his spelling words for 5/12 of an hour. In simplest form, how much longer did Sadie practice than Max?

1/3

Step-by-step explanation:

3/4 - 5/12

Answer

1/3 of an hour longer

Step-by-step explanation:

3/4 - 5/12

3/4 * 3 = 9/12

9/12 - 5/12 = 4/12

4/12 divided by 4 = 1/3

Sadie practiced 1/3 of an hour than Max.

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
