A machine produces 90 decibels of sound power. The inequality 90 + 10 log x ≤ 95 represents the number of identical machines, x, that can be used at the same time and produce less than 95 decibels of sound power. What is the maximum number of machines that can be used at the same time and produce less than 95 decibels of sound power?

3

Step-by-step explanation:

I plugged it into desmos and it said it can go up to 3.16 but you can't have 3.16 machines so it's 3.

10

step-by-step explanation:

7+3=10

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
