Let's put it this way.
It's a ratio of 6:72 and we need to change it in a way to find number of rooms cleaned in 9 days.
Divide 6 & 72 both by 2
Ratio is now 3:36
Multiply 3 & 36 both by 3
Ratio is now 9:108
The number of rooms in which Robin can clean in 9 days is 108 rooms.
The answer would be 537 because if you add 500 and 37 it would be 537 so that is your answer.
Answer:
B) 60
Step-by-step explanation:
5*2*3*2=60 types by multiplying all the categories together.
Answer:f⁻¹(x) =
Explanation:To get the inverse of a function, we have to follow these steps:1- replace f(x) with y
2- swap the x and y variables
3- solve for y
4- replace y with f⁻¹(x)
Applying this to the given as follows:f(x) =
Step 1: replace f(x) with y:y =
Step 2: swap the x and y variables:x =
Step 3: solve for y:7x = 4y - 3
4y = 7x - 3
y =
Step 4: replace y with f⁻¹(x):f⁻¹(x) =
Hope this helps :)
