The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6) Cross Multiply after combining

7 / (x + 7) = 6/(21)

6 * (x + 7) = 7 * 21 Remove the brackets

6x + 42 = 147 Subtract 42

6x = 147 - 42

6x = 105 Divide by 6

x = 17.5

I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.

You do not have enough money to pay your sister back and the amount left is $29

<h3>A. Do you have enough money to pay your sister back? </h3>

The given parameters are:

Amount borrowed = $130

Earnings = $12 per hour for 4 hours

Earnings = $12 per hour for 6 hours

Tip = $5

The total earnings is

Total = 12 * 4 + 12 * 4 + 5

Evaluate

Total = $101

101 is less than 130

Hence, you do not have enough money to pay your sister back

<h3>How much money left</h3>

The amount left is calculated as:

Amount left = $130 - $101

Evaluate

Amount left = $29

Hence, the amount left is $29
