7. Consider the equation + 7 = 13. Part A: Write an equivalent equation using the multiplication property of
equality.
Part B: What properties will you use next to solve the equation?

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).

Sum is 17 and their difference is 3

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
