Answer:
6 percent
Step-by-step explanation:
1 ) 360/9 = 40 - 40 dollars earned per month
2) 40 x 12 = 480 - earned per year
3) 6000/9 = 666.67 x 12 = 8000 per year
4) 480/8000 = 0.06 / 6 percent
Lets check: 6000 x 1.06 = 6360 which is the amount of interest she gets paid in 9 months
Lessons = (120-45)/15 = 5
They can afford 5 hours of lessons,
Hope this helps! :)
Answer: The length of PQ is 37 KM
Step-by-step explanation:
(x+15) + 3(x+15)+ x=245
distribute
(x+15) + 3x+45+x
remove parenthesis
x + 15 + 3x + 45 + x
Add like terms
5x + 60 = 245
Subtract 60 from both sides
5x + 60 - 60 = 245 - 60
5x = 185
divide by 5
x = 37
