3x+3y=180 what is the answer to this problem
Hatshy [7]

Answer:

If you are solving the equation for x :

3x + 3y = 180

3x = -3y + 180

x = -y + 60 or x = 60 - y

If you are solving the equation for y:

3x + 3y = 180

3y = -3x + 180

y = -x + 60 or y = 60 - x

Emily meal cost 32.75 and Darren's meal cost 39.88 . Emily treats Darren by paying for both meals,and leaves 14% tip. Find the t
tia_tia [17]
32.75 + 39.88   = 72.63

72.63 x 114%  = 72.63 x 1.14  = $82.7982   or $82.80 to the nearest cent.

114%  is all of the cost of the meal plus 14 % extra for the tip.  See how muliplying by 1.14 includes the $72.63  (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
