Help Will mark brainliest if correct. The loudness L of sound in decibels is given by L=10 log (L/Lˇ0) where L is the intensity of sound, and Lˇ0 is the intensity of the least audible sound. If Lˇ0=10^-12W/m^2 about how many times more intense is a 97 decibel sound than a 93 decibel sound?

21

jk it's 20

step-by-step explanation:

c

-by-step explanation:

it would be c

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated
