Answer:
Step-by-step explanation:
She took 29 classes in total
16 because 48/3 = 16 and we know that he started with 50 chocolates then distributed 3 times the number of friends present. This is written as 50 - 3x. We also know that there were 2 chocolates left so -3x = 2 - 50 which when simplified is x = 48/3 which equals 16.
Answer:
Infinitely many solutions
Step-by-step explanation:
Left side:
When you distribute 1/2 to the equation in the parentheses, it will be 3x-3/2.
Right side:
When you distribute 1/4 to the equation in the parentheses, it will be 3x-6/4.
6/4 can be reduced to 3/2 so it'll be 3x-3/2.
This means that the reduced form will be 3x-3/2=3x-3/2
Since the 2 sides have the same equation, there will be infinitely many solutions.
