Answer: x = 8.4
Work: So, the goal of this equation is to get x by itself, and the first thing we need to do is get 22 out of that current side. To do that, we are going to add 22 on both sides, cancelling it on the side it's currently on. So, the new equation is 5x = 42. Now, we need to divide 5 on both sides, and like I said, I'll cancel on the side it's currently on. So, the answer is x = 8.4

Hello there,
First off what is scientific notation?
Scientific Notation is<span> the way that scientist handle very large or very small numbers..
</span>for example, instead of writing 0.0000000056 we write 5.6x10 (exponent -9)
So, now we got that out the way lets look up here at the choices....
I would say that 7.8x10 (exponent -5) would be the answer! :)
I hoped this helped!!!! :)))
God bless you.
You are correct, it is alexander the great
I hope I've helped!
Answer:
The time of a commercial airplane is 280 minutes
Step-by-step explanation:
Let
x -----> the speed of a commercial airplane
y ----> the speed of a jet plane
t -----> the time that a jet airplane takes from Vancouver to Regina
we know that
The speed is equal to divide the distance by the time
y=2x ----> equation A
<u><em>The speed of a commercial airplane is equal to</em></u>
x=1,730/(t+140) ----> equation B
<u><em>The speed of a jet airplane is equal to</em></u>
y=1,730/t -----> equation C
substitute equation B and equation C in equation A
1,730/t=2(1,730/(t+140))
Solve for t
1/t=(2/(t+140))
t+140=2t
2t-t=140
t=140 minutes
therefore
The time of a commercial airplane is
t+140=140+140=280 minutes
Answer:
60 degrees
Step-by-step explanation:
180 - 120= 60
