Please give answers in simplest form. a) 5/y+1 1/y y-4/y^2 y b) 2/x^2 x 6) 3 x^3 2x^2 3x) Please explain in steps.

you for your effort and time, it is much appreciated. Hopefully this clears question a), It's actually (5/y+1) (1/y) y-4/y^2y). The answer to that is 3/y - 1/y not 1/y

can you do 749.70 100.00 in your head? 849.70 100.00 easy 849.00 what about 158.70 can someone please help me, answer my questionan This persons example is really hard easy way to add and subtract mentally is to memorize the results of adding and subtracting the numbers 0to10 for example, 849.70-150.70=699.00 easy because 0-0=0, 7-0=7, 9-0=9, 4-5=-1 so borrow to make 14-5=9, 8-1=7because we borrowed from 800, 7-1=6 so mental adding and subtracting is pretty much like this. another helpful tip is to memorize mathematical shortcuts, many of which are easily found on the internet
