The wrong step is step 4, because you only need one conversion.
The formula to convers pounds to kilograms is
Obviously, the inverse formula is
So, you're given an input of 142 pounds. To convert it in kilograms, plug that value into out formula:
and this is the answer you're looking for, so you need no more steps.
Ok so a dependent variable is one that depends on the other one
There are 4 * 1/4 hr in one hour so we multiply yhe 3/4 by 4
Answer is 3/4 * 4 = 3 miles
Answer:
x = 1±2i
Step-by-step explanation:
(x - 1)^2 = -4.
Take the square root of each side
sqrt( (x - 1)^2) = sqrt(-4)
Sqrt(ab) = sqrt(a)sqrt(b)
We know the sqrt(4) = 2 and the sqrt(-1) = ±i
x-1 = ±2i
Add 1 to each side
x-1+1 = 1±2i
x = 1±2i
Answer:
