jonas wants to mail a package that weighs 4.2 kilogram. how much dose the package weigh in pounds?
we know that
1 kg = 2.20462262185 lb
1 kg=2.2 lb
we have
4.2 kg
Convert to pounds
so
4.2 kg=4.2*(2.2)=9.24 pounds
therefore
the answer is 9.24 pounds
Answer:
f^(-1)(x) = \frac{-1}{5} (x+4)
Step-by-step explanation:
Given is a function
To find its inverse.
We must check whether f is one to one or onto first
If -5x1-4 = -5x2-4 we get x1=x2
Hence f is one to one
Also for every f(x) we can find a x so f is onto.
So inverse exists
Let
Replace x by f inverse and y by x
Answer:
6 or -2
Step-by-step explanation:
|3t - 6| = 12
3t - 6 = 12
3t = 18
t = 6
3t - 6 = -12
3t = -6
t = -2
Answer:
add x
Step-by-step explanation:
The operation "subtract 5" has eliminated the constant from the right side of the equation, so the next step would be to eliminate the variable from the left side. You do that by adding the opposite of the variable term.
The opposite of the term -x is x, so we "add x" as the next step.
This makes the solution look like ...
-x +6 = 5 -3x
-x +1 = -3x . . . . . . subtract 5
1 = -2x . . . . . . . . . add x
-1/2 = x . . . . . . . . .divide by -2

<em>Comment on this solution</em>
My preference is always to add the opposite of the variable term with the smallest coefficient. Here, that term is -3x, so I would add 3x as a first step. This leaves the only x-term with a <em>positive</em> coefficient, so can reduce errors in the solution.
