Answer:
x +
x = 2x - 25
Step-by-step explanation:
First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:
x +
x
Then it says the last part of the expression is "twenty five less than twice the number"
2x - 25
Then, equal the two parts of the equation to each other.
x +
x = 2x - 25
Hope this helps! :)

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
Answer:
4+(-6)+8+(-1)
Step-by-step explanation:
if she starts at 4 points and her first turn she cuts 6 trees then you can add a negative 6 which is the same as subtracting that 6 when she plants 8 add those points then for her last turn add a negative 1 which is the same as subtracting 1 and she should end up with 5 points.
