Solve for x
please help!

Step-by-step explanation:

As these are alternate angles hence we got that ,

both angles will be equal ,

7x+5 =  47

x= (47-5)/7

x=6 degree

x = 6°

Step-by-step explanation:

7x + 5° = 47°, because of alternate exterior angles (We can use this because the lines are parallel). Since we know this, we can solve for x.

Solving this equation:

7x + 5 = 47 and if you subtract by 5 on both sides you would get that 7x = 42. From here, you divide 42 by 7 to get your answer. 42/7 = 6 so x = 6 degrees.

Note: I assumed that the angle 7x + 5 was 7x + 5°

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
