Question

Plss ans it fast❤️❤️

From the given data calculate y
Dx=39, x=3,Dy=52, y=? ​

Answer 1

Answer:

y=4

Step-by-step explanation:

Dx=39 and given x=3

then D = 39/3

D = 13......(1)

Dy = 52

from (1)

13*y = 52

y = 52/13

y = 4

Answer 2

$\text{ \large{ \underline{ \: \underline{ \: Solution : \: } \: }}}$

$\text{ \underline{ \: \underline{ \: Given :\: } \: }} \\ \star \: \text{Dx = 39 } - - - (1) \\ \star \: \text{x = 3 } \\ \star \: \text{Dy = 52 } - - - (2)$

Putting the value of x in eq (1)

$\: \: \: \: \: \: \: \: \: \: \: \textbf{Dx = 39} \\ \implies \: \text{D}\times \text{3} = 39 \\ \implies \: \text{D} = \frac{39}{3} \\ \implies \: \text{D} = 13 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\textsf{D} = 13}}$

Now, Putting the value of D in eq (2)

$\: \: \: \: \: \: \: \: \: \: \: \textbf{Dy = 52} \\ \implies \: \text{13}\times \text{y} = 52 \\ \implies \: \text{y} = \frac{52}{13} \\ \implies \: \text{y} = 4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\textsf{y} = 4}}$
