Respuesta :

When y equals 5, x is 104.3

When y equals 3 then x is 108.3

Solution:

Given expression is:

[tex]y = 57.15 - 0.5x[/tex]

If y equals 5 what is x ?

Substitute y = 5 in given expression

5 = 57.15 - 0.5(x)

5 = 57.15 - 0.5x

0.5x = 57.15 - 5

0.5x = 52.15

Divide both sides by 0.5

x = 104.3

Thus when y equals 5, x is 104.3

If y = 3 what is x ?

Substitute y = 3 in given expression

3 = 57.15 - 0.5(x)

3 = 57.15 - 0.5x

0.5x = 57.15 - 3

0.5x = 54.15

Divide both sides by 0.5

x = 108.3

Thus when y equals 3 then x is 108.3

When "Y" equals "5" then "X = 104.3"  , when "Y" "equals" 3 then "X = 108.3".

Given:

  • [tex]Y = 57.15 - 0.5 X[/tex]

When Y = 5,

→ [tex]Y = 57.15 - 0.5 X[/tex]

     [tex]5 = 57.15-0.5 X[/tex]

[tex]0.5 X = 57.15-5[/tex]

[tex]0.5 X = 52.15[/tex]

   [tex]X = \frac{52.15}{0.5}[/tex]

       [tex]= 104.3[/tex]

 

When Y = 3,

→  [tex]Y = 57.15 - 0.5 X[/tex]

     [tex]3 = 57.15 - 0.5 X[/tex]

[tex]0.5 X = 57.15-3[/tex]

[tex]0.5 X = 54.15[/tex]

    [tex]X = \frac{54.15}{0.5}[/tex]

        [tex]= 108.3[/tex]    

Thus the responses above are correct.
