Answer:
C) 119.7°
Step-by-step explanation:
got it right on edge :)
3/(x+2) = 2/x
multiply both fractions by x(x+2) to cancel out the bottoms
so it becomes 3x = 2x+4
ow subtract 2X from both sides and you get
x = 4
so it took Juan 4 hours
it took Yumi 2 hours more so 4+2 = 6 hours
Hello! To find any number in the arithmetic sequence we can use a formula!
It is given by

The geometric sequence formula goes by

So for this we notice that there's a start of 5 and is being added 3 to get 8.
and then each time it is added by 2 more to get the next time
5
5+ 3 = 8
8 + 5 = 13
13 + 7 = 20
20 + 9 = 29
29 + 11 = 41
41 + 13 = 54
54 + 15 = 69
69 + 17 = 83
Your formula is

Where n starts at 2 not 1
The answer is c. if you plug in the numbers for x you get the correct numbers for y
