Bumek [7]3 years ago

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

Tim and Caitlin are preparing to get married. Caitlin has a car payment of $300 per month, which is 10% of her monthly income. A
Misha Larkins [42]

Answer:

A. $2,000

Step-by-step explanation:

Let x represent Caitlin's monthly income and y represent Tim's monthly income.

We have been given that Caitlin has a car payment of $300 per month, which is 10% of her monthly income.

We can represent this information in an equation as:

\frac{10}{100}x=300

0.10x=300

x=\frac{300}{0.10}

x=3000

Therefore, Caitlin's monthly income would be $3000.

We are also told that after Caitlin is married to Tim, her car payment will only be 6% of their combined monthly income.

This means that 6% of x plus y is equal to 300.

\frac{6}{100}(x+y)=300

0.06(3000+y)=300

180+0.06y=300

180-180+0.06y=300-180

0.06y=120

y=\frac{120}{0.06}

y=2000

Therefore, Tim's monthly income is $2,000 and option A is the correct choice.

During study:

Sample size = 210

Number of samples who speak 3 or more languages = 14

Proportion who speak 3 or more languages :
