Well, according to PEMDAS, you do what's in the parenthesis first. That would be 4/2, or 2+16 = 18. Next, -6y + y = -5y. That would be 2x^2-5y+18. Is that what you needed?

16 x 12 = 192 plates

496 total plates - 192 = 304

Angles and transversals thank you
faltersainse [42]

Answer:

#11-13: 118 , 97 , 62

#7-10: 92 , 125 , 56 , 130

Step-by-step explanation:

#11. Supplementary angles (A + B = 180)

  • (n + 7) + (3n - 47) = 180
  • n = 55
  • <ABC = 3(55) - 47 = 118 degrees

#12. Supplementary angles

  • 83 + x = 180
  • x = 97
  • <ABC = 97 degrees

#13. Congruent angles (A = B)

  • (8x - 34) = (5x +2)
  • x = 12
  • <DEF = 5 (12) + 2 = 62 degrees

#7. Congruent angles

  • (3x +23) = 4x
  • x = 23
  • <ABC = 4(23) = 92 degrees

#8. Congruent angles

  • 5x = (3x + 50)
  • x = 25
  • <MPQ = 3(25) + 50 = 125 degrees

#9. Congruent angles

  • (a + 28) = 2a
  • a = 28
  • <MNP = (28) + 28 = 56 degrees

#10. Congruent angles

  • 5y = (2y + 78)
  • y = 26
  • <WXZ = 5(26) = 130 degrees

I hope this helps!
