Answer:

B. 40

Step-by-step explanation:

Angle C is linear with ACD, so the 2 angles = 180 degrees. 180 - 155 = 25.

All 3 angles need to add to 180, so 115 + 25 + angle B = 180

140 + angle B = 180, so angle B is 40 degrees.

Which of the following is a solution to the equation x - 5/7 = -3/7
podryga [215]

Solve the equation:

          5              3
x  –  ——  =  –  ——
          7              7


           5
Add  ——  to both sides, so you get  x  isolated at the left-hand side:
           7

          5          5               3          5
x  –  ——  +  ——  =  –  ——  +  ——
          7           7              7           7

              3          5
x  =  –  ——  +  ——
              7           7


Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x  =  —————
               7

          2
x  =  ——     <———    this is the answer (first option:  2/7).
          7


I hope this helps. =)
