Solve for the variable in each equation by doing the same math on both sides of the equal sign. After isolating and solving for the variable, state which property of equality you used addition, subtraction,
multiplication, or division).

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

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

what is the question?

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
