  (∗)

1/(1−t)=∑0∞tn   (∗)

where  

|t|<1

|t|<1

. I mean take  

t=−x/3

t=−x/3

and...

Note that  

|−t|=|t|<1

|−t|=|t|<1

Eduardwww [97]

Answer:

7 Hours

Step-by-step explanation:

Given The lawyer charges $100 per month for a client.

Also he charges $75 per hour

The total money the lawyer charged is $625

total money = monthly charges + hourly charges

625=100 + 75x

75x=525

x=525/75=7

Therefore the lawyer has to work for 7 hours to charge $625

katelyn bought 5.68 pounds of peaches. the peaches were on sale for 1.49 a pound. how much did lately spend on peaches
Leya [2.2K]
So Katelyn bought 5.68 pounds of peaches. And one pound of peaches cost $1.49. So that would mean that we would have to multiply the pounds of peaches she bought, with how much each pound costs. 5.68 × 1.49 = ?

Once you multiply these two decimals, you would get 8.4632. So she spent $8.4632 on 5.68 pounds of peaches. You would multiply the two decimals to find how much she spent in all.
