Please someone help me finish filling in the rest :( feel like I’m finna cry

Let the number be x in all those expressions.

15 - x = 20 - 7

or, x = 15 - 13 = 2

x + 2 = 16 + 3

or, x = 19 - 2 = 17

13 - 6 = x - 9

or, 7 + 9 = 16 = x

10 • 6 = 15 • x

or, 60/15 = 4 = x

10 ÷ x = 20 ÷ 4

or, 5 × 10 = 50 = x

18 • x = 16 • 9

or, x = 144 / 18 = 8

16 • 9 = 18 • x

or, x = 144 ÷ 18 = 8

10 ÷ 2 = x ÷ 2

or, x = 10 × 2 = 20

Step-by-step explanation:

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

answer: 193

explanation:

200-7 = 193
