7/4

Step-by-step explanation:

the value of x is [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

the inverse variation equation XY=k

Given the value of y=4  and k=7

Plug in all the values in the given equation and solve for x

x* y = k

x * 4 = 7

Divide by 4 on both sides and solve for x

[tex]x=\frac{7}{4}[/tex]

So the value of x is 7/4

7,4 is the answer to the question

[tex]x=7/4[/tex]

Step-by-step explanation:

the equation is:

[tex]xy=k[/tex]

To find the value of [tex]x[/tex], we need to substitute the values that we know for [tex]y[/tex] and [tex]k[/tex]:

[tex]y=4[/tex]

and

[tex]k=7[/tex]

so, we substitute this values into the equation

[tex]xy=k[/tex]

[tex]x(4)=7[/tex]

and we clear for [tex]x[/tex], for this we move the 4 to the right dividing:

[tex]x=7/4[/tex]

The value of x is [tex]\frac{7}{4}[/tex].

Step-by-step explanation:

Inverse variation is defined by the equation

[tex]xy=k[/tex]

It is given that the value of y is 4 and the value of k is 7.

Substitute [tex]y=4[/tex] and [tex]k=7[/tex].

[tex]x(4)=7[/tex]

Divide both sides by 4.

[tex]\frac{4x}{4}=\frac{7}{4}[/tex]

[tex]x=\frac{7}{4}[/tex]

Therefore the value of x is [tex]\frac{7}{4}[/tex].

The value of x is [tex]\frac{7}{4}[/tex].

Step-by-step explanation:

It is given that the inverse variation equation is

[tex]xy=k[/tex]                  ..... (1)

The value of y is 4 and the value of k is 7.

Substitute y=4 and k=7 in equation (1).

[tex]x\times 4=7[/tex]

Divide both sides by 4.

[tex]\frac{x\times 4}{4}=\frac{7}{4}[/tex]

[tex]x=\frac{7}{4}[/tex]

Therefore the value of x is [tex]\frac{7}{4}[/tex].

It would be 7/4 or 1.75 if needed to be in decimal format.

Xy = k
4x = 7
Divide both sides by 4
x = 7/4

B,) 7/4
