Adelle solved the equation 4x/7 -6 = -20 as shown. fill in the justification for each step.

4x/7 -6= -20 =given
4x/7 = -14 = ?
4x = -98 = ?
x = -24.5=?

Can anyone me with 32,33,36,37,and 40.

Write the expression as a single natural logarithm. 2 in a - 4 in y

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
