Answer:

2 possible answers

Step-by-step explanation:

Assumption: 178 wore black (that means some may wear gold + black aka as long as they wore abit of black, it's counted):

since there are 257 students and 34 wore both gold and black, and 178 wore black, the number of students who wore only black = 178 - 34 = 144

no of students who wore only gold = 257 - 144 - 34 = 79

Assumption: 178 students wore ONLY black:

no of students who wore only gold: 257 - 178 - 34 = 45

Solve for x..................
Yanka [14]

Answer:

x = 4

Step-by-step explanation:

(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.

Knowing that, we can do the following:

  • (5x+19) + (5x+131) = 180
  • 5x + 19 + 5x + 131 = 180
  • 10x + 140 = 180
  • 10x = 40
  • <em>x = 4</em>
