Answer:
x = 9/2 - 15/2
Step-by-step explanation:
That makes no sense. Can you rephrase the question?
Not to good with math but the answer may be B
The answer is x=5. I've included the work in the picture attached.
If Nico gave away some red circles and you would like to know how many red circles does he have left, you can calculate this using the following step:
Nico has 15 red circles.
n ... the number of red circles that he gave away
15 - n ... the number of circles that Nico still has
The correct result would be 15 - n.
