Simplify and solve the equation 1/3x+3=4

X = 1/3

Step-by-step explanation:

Multiply all terms by x and cancel:

1

+3x=4x

3x+

=4x(Simplify both sides of the equation)

3x+

−4x=4x−4x(Subtract 4x from both sides)

−x+

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

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
