the order of letters RST corresponds with UVW, where R-U, S-V, T-W

Answer:
13,62$
Step-by-step explanation:
The total hours Riley worked last week: 7.5*3= 22.5 (hours)
Riley's hourly rate of pay: 306.45/ 22.5= 13.62$
6x + 3(3x - 5) = 15
6x + 9x - 15 = 15
15x = 15 + 15
15x = 30
x = 30/15
x = 2
y = 3(2) -5
y = 6-5
y = 1
Solution: (2,1) and x = 2
