Ok can you help with this? The sum of three numbers is 3. The first number minus the second number plus the third number is -3.
The first number minus the third number is one more than the second number.
What are the first second and third numbers?​

x = 2, y = 3, z = -2

Step-by-step explanation:

Set first number a x, second as y, third as z.

x + y + z = 3

x - y + z = -3

x - z - 1 =  y

Plugging y in, we have 2x -1 = 3 and 2z + 1 = -3

So 2z = -4 and z = -2. Then, 2x - 1 = 3 so x = 2. And then y = 3

You can check them to make sure

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
