Evaluate 5x-\dfrac xy5x−

olga2289 [7]

Answer:

5x - (x/y) = 18 when x=4 and y=2

Step-by-step explanation:

5x - (x/y)

When x=4 and y=2

Substitute the value of x=4 and y=2 into the expression

5x - (x/y)

5(4) - (4/2)

Multiply 5 by 4 and divide 4 by 2

=20 - 2

Subtract 2 from 20

=18

5x - (x/y) = 18 when x=4 and y=2

If 83 : 45 :: 72 : ? solve and find the answer

olga55 [171]

Answer: $x=\dfrac{3240}{83}$

Step-by-step explanation:

Given: 83 : 45 :: 72 : ?

Let unknown quantity (?) be x.

Now, x : y :: a : b

$\Rightarrow\ \dfrac{x}{y}=\dfrac{a}{b}$

83 : 45 :: 72 : x

$\Rightarrow\ \dfrac{83}{45}=\dfrac{72}{x}\\\\\Rightarrow\ x=\dfrac{72}{83}\times45\\\\\Rightarrow\ x=\dfrac{3240}{83}$

Hence, $x=\dfrac{3240}{83}$
