Step-by-step explanation:
Let be "x" the amount of miles light will travel in 4,200,000 seconds.
Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:
According to the exercise, light travels
miles in 1 second.
Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.
(Remember the Product of powers property:
)
Then:

Clockwise 180 degree rotation
Answer:
X=65
Y=40
Step-by-step explanation:
2x+10=140
-10 -10
2x=130
÷2 ÷2
x=65
Y=180-140
Y=40
