Answer:

  • Q6. x = 17
  • Q8. Yes, parallel
  • Q9. No, not parallel

Step-by-step explanation:

Q6. Solve for x

<u>Use ratios of similar sides</u>

  • 28/(82 - 28) = (2x + 8)/(5x - 4)
  • 28/54 = (2x + 8)/(5x - 4)
  • 14/27 = (2x + 8)/(5x - 4)
  • 14(5x - 4) = 27(2x + 8)
  • 70x - 56 = 54x + 216
  • 70x - 54x = 56 + 216
  • 16x = 272
  • x = 272/16
  • x = 17

Q8

If ratios are same, the lines are parallel

  • 41.8/33 = (102 - 45)/45
  • 41.8/33 = 57/45
  • 41.8*45 = 33*57
  • 1881 = 1881

Yes, lines are parallel

Q9

  • 38/19 = 52/24
  • 2 = 2 1/3

Incorrect, lines are not parallel

Q5. The ratio of boys to girls in a group is 7:1. If there are 48 more boys
Airida [17]

Answer:

There are 8 girls

Step-by-step explanation:

We see that right now there are 6 more boys than girls and if there were 2 girls there would be 14 boys meaning there would be 12 more boys than girls if you continue in this pattern you would get-

7:1= 6 more boys                   35:5=30 more boys                                                

14:2= 12 more boys                42:6= 36 more boys

21:3=18 more boys                 49:7= 42 more boys

28:4= 24 more boys               56:8= 48 more

This shows us that if there are 8 girls in  group there are 56 boys meaning there are 48 more boys than girls if the group had 8 girls
