3. Tank A has 35 gallons of water and is filling up at a rate of 5 gallons per minute. Tank B has 100 gallons of water and is draining at a rate of 8 gallons per minute. The system of equations y = 35 + 5x
can be used to represent this situation. In how many minutes will the tanks contain the same amount of
water, and how much water will that be ?

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).
