Plz help this is my last math question I need help with!

He buys 8 desks and 6 chairs can i have branliest

Step-by-step explanation:

Set up a system of equations

desks = y chairs = x

x+y=14

125x + 515y = 4870

Eliminate,

-125x -125y = -1750

125x + 515 y = 4870

390 y = 3120

y = 8

substitute in 8

x + 8 = 14

x = 6

Step-by-step explanation:

Let number of chairs be x and number of desks be y

Total number of chairs and desks = 14

x + y = 14   (i)

Total cost  = $ 4870

125x + 515y = 4870 (ii)

Multiply equation (i) by (-125).

(i)*(-125)          -125x - 125y = -1750

(ii)                    125x +515y = 4870    {Now add}

                                  390y = 3120

y = 3120/390

y = 8

Plug in value of y in equation 1

x + 8 = 14

x = 14 - 8

x = 6

Number of chairs = 6

Number  of desks  = 8

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
