Solve the system of equations.
3x-4y=8
18x-5y=10

y = -2    x = 0

Step-by-step explanation:

1. 3x-4y = 8

2. 18-5y = 10

Multiply equation 1 by 6

3. 18x-24y = 48

Subtract equation 2 from equation 3

4. -19y = 38

        y = 38/-19

        y = -2

Sub y = -2 back into equation 1

      3x-4(-2) = 8

      3x + 8 = 8

      3x = 0

      x = 0/3

      x = 0

what is the original number? you forgot to add it.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
