Answer:
15s
Step-by-step explanation:
Write like so:
54m = 9s
90m = x
Cross multiply:
(90*9)=(54x)
810 = 54x
Divide both sides by 54:
810/54 = 54x/54
15 seconds = x
Answer:
5 weeks
Step-by-step explanation:
Let x represent the number of weeks they have been saving
Create an equation that sets Cameron and Sams' savings equal to each other, then solve for x
4x + 20 = x + 35
3x + 20 = 35
3x = 15
x = 5
So, they will have saved the same amount of money after 5 weeks
Answer:
f(x) = 3900 * (1 - 0.35)^x
0.5 days = 12 hours
f(12) = 3900 * (1 - 0.35)^12 = 22.18
