please help me im temporally brain dead or at least feel brain dead and i am having trouble understanding this

you should know: in all means in total, so simply you add everything up.

1 + 2/4 + 3/4

- convert 1 to a fraction so its easier to add.

1 = 4/4 (must have the same denominator to add)

4/4 + 2/4 + 3/4

- add the numerators (top), NOT the denominators (bottom)

you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)

9/4 = 2 1/4

FINAL ANSWER: (its a mixed number)

2 1/4

-- let me know if you have any questions regarding this.

18

step-by-step explanation:

ik this stuph and i am smart donkey

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
