Answer: x= −
2.3 and the total equation looks like this: 9(-2.3) + 8.0 = -12.7
2t + 5b = 20
8t + 3b = 29
Multiply the first equation by-4
-8t -20b = -80
8t + 3b = 29
-17b = -51
b = 3
Plug 3 in for b into either equation and solve for t.
2t + 5(3) = 20
2t + 15 = 20
2t = 5
Divide both sides by 2
t = 2.50
Answer:
Final answer is 
.
Step-by-step explanation:
We have been given an infinite geometric series.
Now we need to find it's sum.
common ratio 
.
plug n=1 to get the first term
Now plug these values into infinite sum formula
Hence final answer is .
Answer:
3
Step-by-step explanation:
write them out least to greatest- 1 2 3 4 5
then mark out one at a time from front and back- 1 2 3 4 5
then you get one number and that number is 3
Answer: 5 hours
