Step-by-step explanation:
73.
18 = 3x
(divide both sides by 3 )
6 = x ( multiply both sides by )
6 = 3x [ × = 3 ]
divide both sides by 3
x = 2
74.
24 = 2x
( divide both sides by 2 )
12 = x ( multiply both sides by )
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18 ( divide both sides by 9 )
x = 2
76.
2 = x × 
( multiply both sides by )
2 = 4x ( divide both sides by 4 )
x = 
Answer:
2/5
Step-by-step explanation:
Answer:
f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:
To find inverse of a function , replace f(t) with y
replace t with y and y with x
solve for y
divide both sides by 100
take ln on both sides
divide both sides by ln
multiply by 3 on both sides
Replace x with t and y with f^-1
f^-1 represents the number of hours the bacteria developed
$42,500 because 45900 dividede by 1.08 is 42500
