36; 351; 66; 1,017; 113,331; 1,968; 537; 417; 3,813
Answer:
Approximately 11.99 years
Step-by-step explanation:
This is just a type of problem like finding how long it will take for you to get somewhere. Like in finding how fast you need to go to go to a place that is 60 miles in one hour. All you have to do is divide the distance of the star by the speed of light, and you get the amount of time it will take for the star's light to reach the Earth.
To find decimal form, you first have to change 1/4 into a decimal. That equals 0.25. The percentage would be 6.25%. Now to find the decimal equivalent, move the decimal two places to the left. To fill in the one missing place, add a zero before the 6. Therefore, 6 1/4% is equal to 0.0625 in decimal form.
4x – 2 + x = 3x + 8 + 3x
Combine like terms:
4x+x-2=3x+3x+8
5x-2=6x+8
Move 6x to the other side. Sign changes from +6x to -6x.
5x-6x-2=6x-6x+8
5x-6x-2=8
-x-2=8
Move -2 to the other side.
-x-2+2=8+2
-x=10
Multiply both sides by -1.
(-1)(-x)=(10)(-1)
x=-10
Answer: x=-10
