If you rub it, you will experience 'friction' ...

If you want a 'fraction'  , try clicking on the little grey bars in the far right of the display and select "Fractions"

You will not be able to find the value of 'x' without an '=' sign in your equation, but you can simplify the expression.

Collect all of the like terms together

(4x+7x+16x) + (9-5-27)

27x-23

Bike World cost would be    25 + 8t    where t= time i hours

Canoe Shack cost               10 + 14t                                

Assuming the deposit is part of the cost (it is not returned) find when the two costs are =

25+8t = 10 + 14t    and solve for t

15 = 6t

t= 2.5 hours

IF the deposit is RETURNED when the bikes are returned , the costs will NEVER be the same.

If they were all just mixed together and blindly handed out then

235/752  is the fraction of the total that is white

235/752  x  160 = the fraction of the 160 that were handed out that are white = 50

WHAT is not 'working' ?   You have THREE variables (a,x,y) and only TWO equations.....do you need to solve for 'x' in terms of 'a' ?

....or do you have a value for 'a' ??

is that  e-1    or e^(-1) ???

E = 600 +(.08) s   will tell you how much he makes in a week (E)

1560 = 600 + (.08) s       Solve for 's'  (sales)

960 = .08 s

960/(.08) = s = $ 12,000   in sales needed

sqrt(300) = sqrt(100 x 3) = 10 sqrt(3)

Use the   \(x^{y}\)   button.
