Hope this helps :)

25/8 or 3 1/8

Step-by-step explanation:

5/8 * 5/1 (aka 5)

5/1 equals to 5 because any whole number over 1 equals the same whole number.

To multiply fractions, just multiply across. In the case. 5 time 5 for the numerator. Then 8 times 1 for the denominator.

just took the test

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
