Answer:
I owed a friend 15 bucks till someone payed for me 2/3 of what I owed so I only had to pay him back 5 bucks.
This is a system of equations problem.
L = Hours of Swim Lessons
C = Hours as Cashier
L + C = 15 This is an equation for working 15 hours total.
so
L = 15-C
6L + 8C = 100 This is an equation for making at least $100.
so
6 (15-C) + 8C = 100 *You substituted 15-C for L here
90 - 6C + 8C = 100 Distribute
90 + 2C = 100
2C = 10
C = 5 You can work 5 hours as a cashier
L + C = 15
L + 5 = 15
L = 10 You can work 10 hours teaching swimming lessons.
If you want to make EXACTLY $100 you would work 5 hours as cashier and 10 hours teaching swimming lessons.
HOWEVER, the question says AT LEAST $100 and NOT MORE than 15 hours per week. Since you make more money as a cashier, any work over 5 hours will help you make over $100.
As long as you work at least 5 hours as a cashier and any remaining hours teaching swimming lessons, you will make over $100.
5 cashier, 10 swimming
6 cashier, 9 swimming
7 cashier, 8 swimming...

The values of VT and ST for the given rectangle are 13 and 23.56 respectively.
The given parameters:
- <em>RV = x + 6</em>
- <em>US = 5x - 9</em>
- <em>RS = 11</em>
The value of VT and ST is calculated as follows;
<em>from the given </em><em>diagram </em><em>we can conclude the following;</em>
2RV = RT = US
RT = 2RV = 2VT = 2(7 + 6) = 26
VT = ¹/₂ x 26
VT = 13
The value of ST can be determined from Pythagoras theorem as follows;
