Solve for X. This is geometry I really need help please please.

x = 5.2

Step-by-step explanation:

x/(13-x) = 2/3

3x = 2(13 - x)

3x = 26 - 2x

3x + 2x = 26

5x = 26

x = 26/5

x = 5.2

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
