What is 2 3/4 a = 19 1/4 pls i need an answer asap

Hey there!

2 3/4a = 19 1/4

11/4a = 77/4

MULTIPLY 4/11 to BOTH SIDES

4/11 * 11/4a = 4/11 * 77/4

CANCEL out: 4/11 * 11/4 because it gives you 1

KEEP: 4/11 * 77/4 because it helps solve for the a-value

NEW EQUATION: a = 4/11 * 77/4

SIMPLIFY IT!

a = 7

Therefore, your answer is: a = 7

Good luck on your assignment and enjoy your day!

step-by-step explanation:

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
