What is 3/5+3/4? Whats the totallt

27/20

(1.35 decimal form)

Step-by-step explanation:

make the common denominator 20, since it is the LCM

12/20+15/20= 27/20

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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
