27. What number plus one half is equal to three eighths?

Let the un know number be p

p + 1½ = 3/8

p + 3/2 = 3/8

p= 3/8 – 3/2

p= –9/8✅

Step-by-step explanation:

x + ½ = ⅜

x + ½ - ½ = ⅜ - ⁴/₈

x = - ⅛

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
