A large brine tank containing a solution of salt and water is being diluted with fresh water.
kirza4 [7]

Answer:

41.04 g/L

Step-by-step explanation:

The relationship is modeled by the following function:

S(t) = 500*e^(-0.25*t)

where t is time elapsed after the dilution begins (in hours) and S(t) the concentration of  salt in the tank (in g/L)

Replacing with t = 10

S(t) = 500*e^(-0.25*10)

S(t) = 41.04 g/L

5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying

5x + 8 = ?

If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8

45 + 8 = 53

Therefore 5x + 8 = 53

Hope this helps you! :)
