Answer:
The total pieces of cake are 24
Step-by-step explanation:
Linear equations
It's a relation between one or more variables and or numbers, connected with the equal sign. An example is 4x-5=7, or 2(x+y)=7-(x-y)
This problem can be easily solved without the use of equations, but we are required to.
We know Mindy and Troy combined ate 9 pieces of cake, we also know that Mindy ate 3 pieces of cake. It leaves 6 pieces to Troy. Since Troy ate 1/4 of the whole cake, then
[tex]\displaystyle \frac{1}{4}X=6[/tex]
Where X is the number of pieces of cake
Solving for X
[tex]X=(4)(6)=24\ pieces[/tex]
