Answer:
<em>Rate of Pratap in still water is 4.5 miles/hour and rate of current is 0.5 miles/hour.</em>
Step-by-step explanation:
Pratap Puri rowed 10 miles down a river in 2 hours, but the return trip took him 2.5 hours. 
We know that, 
So, the <u>speed of Pratap with the current</u> will be:   miles/hour
 miles/hour 
and the <u>speed of Pratap against the current</u> will be:   miles/hour.
 miles/hour. 
Suppose, the rate of Pratap in still water is  and the rate of current is
 and the rate of current is  .
. 
So, the equations will be........

Adding equation (1) and (2) , we will get......

Now, plugging this  into equation (1), we will get.....
 into equation (1), we will get.....

Thus, Pratap can row at 4.5 miles per hour in still water and the rate of the current is 0.5 miles/hour.
 
        
             
        
        
        
Answer:
The drama club bought 35 t-shirt
Step-by-step explanation:
Let
t-shirt = x
Sweatshirt = y
Total cost = $795
They purchase 20 more tshirts than sweatshirts
x = y + 20
The equation is:
12x + 25y = 795
12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y = 555
y = 15
Substitute y = 15 into
x = y + 20
x = 15 + 20
x = 35
t-shirt = 35
Sweatshirt = 15
The drama club bought 35 t-shirt

Answer: 4/3 
Step-by-step explanation:
You would find this answer because if x is 0 then it is just 2 then when you multiply 3 x 4/3 you get 4 then when you add that by two you get 6 
Hopes this helps
