Jose combined the like terms in the expression. Marc claims that he made a mistake. Negative 8 x squared y minus 17 x y squared + 12 x y minus 8 + 5 x squared y minus x y squared minus 12 x y = negative 3 x squared y minus 18 x y squared + 24 x y minus 8 Jose asks Marc to explain how to fix his error. Which is the best explanation that Marc can give Jose?

y=-2x+1500

step-by-step explanation:

+1500

2 over one

she made 48 + y = a cookies.     not enough info is given to find the total.

the answer is $4.45. i started by figuring out the cost of the plates and napkins. the easiest way to figure this cost out is through the tax. we know the way they found the tax is by multiplying the cost of non-food items by the tax rate (5% or 0.5). so, all we have to do to find the cost before tax is set up an equation and work this formula backwards. the equation is 0.19=0.05x where x is the cost of the plates and napkins. now all you do is divide both sides by 0.05 to come up with 3.8=x. now that we know the cost of the plates and napkins is $3.80, all we have to do is subtract this cost from the total cost of $8.25 giving us the cost of the watermelon which is $4.45.
