Work shown above! Answer would be A!
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.
Solving, we get 40 = 2x, x =20
The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.
Hope this helped!
Use photo math app it will help you
The second one 1.7 = 17/10
-0.048 = -6/125
98% = 98/100= 49/50
Ok so given the point (r, theta)
The corresponding Cartesian point is (r*sin(theta), r* cos(theta)) you can think about this by analyzing the points on a unit circle which is a graph of a polar circle with radius 1 and angle theta
That would be 8. 1/4 goes into 1 4 times so it goes into 2 8 times.
