I think it’s 60 if NP is the same arc as MN.. 120/ 2 = 60
Answer:
I know you have to do s=d/t so 42/225=0.18
I would say D. 7+4 because it is the only one that makes since to me
Mass = density x volume
Mass = 178 x 25 = 4,450 grams
3x + 2y + y - 3x = 180
3y = 180
y = 180/3
y = 60
3x = y - 3x
Let y = 60
3x = 60 - 3x
3x + 3x = 60
6x = 60
x = 60/6
x = 10
Answer: x = 10, y = 60
