Mindy and Troy combined 9 pieces of the wedding cake. Mindy ate three pieces of cake and Troy had 1/4 of the total cake

write an equation to determine how many pieces of cake (c) there were in total

Mindy and troy combined 9 pieces of the wedding cake.

Mindy ate = 3 pieces of cake

Troy = had ¼ of the total cake.

Now, let’s find an equation that will give us the total number of pieces of the cake

=> Let X = Mindy

=> let Y = Troy

=> Let c = total number of cake

=> X + Y = 9, where x = 9 and y = ¼

Let’s find the number of pieces of cake that Troy’s have:

=> Y = 9 - x

=> Y = 9 - 3 = 6

=> Y = 6

Now, let’s find the number of Cake

=> 6 = c/4

=> c = 4 x 6

=> c = 24

Thus, there are 24 cakes in all.
