Deva bought 9 1/2 m of cloth for rupees 28 1/2.Samruth buys 26 1/3 m of same cloth. how much should samruth pay the shopkeeper?
likoan [24]

For this case we can make the following rule of three:

9 1/2 m --------------> 28 1/2 rupees

26 1/3 m -------------> x

From here, we clear the value of x.

We have then:

x = (\frac{26+\frac{1}{3}}{9+\frac{1}{2}}) (28+\frac{1}{2})

Rewriting we have:

x = (\frac{\frac{79}{3}}{\frac{19}{2}}) (\frac{57}{2})

x = (\frac{158}{57}) (\frac{57}{2})

x = \frac{158}{2}

x = 79

Answer:

samruth should pay 79 rupees to the shopkeeper

√9a^2 + √49b - a + √b<br><br><br> a. 2b + 8 √a<br><br> b. 2a - 8 √b<br><br> c. 2a + 8 √b
Firdavs [7]
The correct answer:
______________________________________________________
Explanation:
______________________________________________________
Assuming you mean:

" √(9a²)  +  (√49b)  −  a  +  √b " ;

Simplify the expression:
_________________________________________________________

Note that:  " √(9a²) = 3a " ;

                   "√(49b) = 7√b " ;   

And we write the expression

   →  " 3a  +  7√b  −  a  + √b " ; 

Combine the "like terms:

   " + 3a − a  =  2a " ;

   " +  7√b  +  1√b   =  8√b " ; 

Rewrite:  
________________________________________________________
    " 2a  +  8√b " ;  which is:  Answer choice:  [C]:  " 2a  +  8√b " .
