Answer: 5 people
Step-by-step explanation:
The easiest way to do this is to set up a proportion. 6/12=x/10. To solve, cross-multiply and divide. Multiply 6 and 10 (6*10=60) and divide by 12 (60/12=5).
You can also find that 6/12 is equal to 1/2 by dividing each side by 6. Then multiply 10 by 1/2 (or divide 10 by 2) to get the final answer of 5 people.
15 * 1/3x = 5x
15 * 5 = 75
5x + 75 is the simplified expression
20-14=6
14 have average of 2.
total mass of the 14=14×2=28lb
remaining 6 have average of 4.
total mass=4×6=24lb
total mass of the 20=28+24=52lb
average of the 20;
52/20=2.6lb
