A sum of $900 is shared among Nas, Sam and Kristine in the ratio p: 5: 7. If Nas receives $120, what is the value of p?​
weqwewe [10]

Answer:

p+5+7=p+12

p/(p+12) ×900=120

900p=120(p+12)

90p=12(p+12)

90p=12p+144

90p-12p=144

78p=144

p=144/78

I would appreciate if my answer is chosen as a brainliest answer
