4 0

Answer:

21/4

Step-by-step explanation:

21 y = -4x           Divide 21 on both sides

y = -4/21x            Slope is -4/21

Perpendictulare lines have a slope that are the negative inverses of eachother, so flip the 4 and the 21 and make it positve instead of negative

if 10 operators worked on 120 pages for 2 hours

P operators will work on the same pages for 30min

note: 2hrs= 120min

10×120min/120= P × 30/120

  • cross multiply
  • make P subject of the formula

P= 10×120×120/120×30

P = 40 operators
