26 sit ups in 2 minutes . find the unit rate and how many in 5 minutes

Unit rate: 13 sit ups per minute

65 sit ups can be done in 5 minutes

Step-by-step explanation:

Find the unit rate by dividing 26 by 2

26/2

= 13

This means 13 sit ups can be done in 1 minute.

To find how many can be done in 5 minutes, multiply 13 by 5.

13(5)

= 65

So, the unit rate is 13 sit ups per minute, and 65 sit ups can be done in 5 minutes.

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

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
