This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence:

If a1=1.6 then:

The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
Answer:
or 
Step-by-step explanation:
<u><em>The correct equation is</em></u>

solve for x
Multiply by 8 both sides to remove the fraction

subtract 15 both sides

divide by 8 both sides


Answer:
2.50t + 350 = 3t + 225
Step-by-step explanation:
Let t represent the number of tickets that each class needs to sell so that the total amount raised is the same for both classes.
One class is selling tickets for $2.50 each and has already raised $350. This means that the total amount that would be raised from selling t tickets is
2.5t + 350
The other class is selling tickets for $3.00 each and has already raised $225. This means that the total amount that would be raised from selling t tickets is
3t + 225
Therefore, for the total costs to be the same, the number of tickets would be
2.5t + 350 = 3t + 225
