I believe it would be $6 because both numbers can be divisible by 3. after you do that you would be left with 0.5 pounds = $3 after that you would divide 1 by 0.5 and get 2 then multiply that by 3 which is 6
Answer:
Step-by-step explanation:
Given
Required:
Find
Replace f(x) with y
Swap both variables
Make y the subject
Replace y with f-1(x)
Answer:
[-1.8], [2.7], 3 2/5, [3.5]
thats the answer
2 1/3 + 1 3/4 = 2 4/12 + 1 9/12 = 3 13/12 = 4 1/12
Answer:
2
Step-by-step explanation:
In general, .
So we have here that:
We went by itself first.
Subtract 441 on both sides:
Multiply both sides by -1:
Take the square root of boht sides:
So both 2 and -2 would satisfy the equation.
Only one of these is a whole number.
The whole numbers consist of the elements that you can count with and 0.
The whole number set is {0,1,2,3,4,5,6,7,...}
So 2 is the answer.
Check:
Replace x with 2:
437=(21+2)(21-2)
437=(23)(19)
437=437 is a true equation so 2 is definitely a solution.
