How many calories is a slice of ice cream cake


Asked by wiki @ in Mathematics viewed by 138 People


the number of calories in a piece of cake is 20 less than three times the number in a scoop of ice cream. the cake and the ice cream together have 620 calories. how many calories are in each

Answered by wiki @



To solve this we must set up a system of equations where x is the number of calories in a peice of cake, and y is the number of calories in a scoop of ice cream. when we do this, we get x=3y-20 and x+y=620. So, to solve this sytem, you can use many methods, but I will use substitution. if we substitute the first equation for x in the second, we get 3y-20+y=620. solving for y, we get y=160. then substituting this in to the first equation, we get x=460. So the answer is there are 460 calories in a peice of cake and 160 calories in a scoop of ice cream.

Do you know the better answer?
