Answer:
16
Step-by-step explanation:
This question can be modeled using the equation 3x+4=52 (x is the purple marbles). To solve this equation subtract 4 from both sides, making it 3x=48. divide both by three showing x=16. This shows that 16 is the answer.
Answer:
x=1.5
Step-by-step explanation:
You divide 8 by 8 and then -12 by 8. And then you get x=-1.5 because 8 divided by 8 is zero and -12 divided by 8 is -1.5
The formula of that is 24
