Okay.. well did you try to do it on your own at least ? I help you, but what do you know already so we can go on from there.
Answer:
Step-by-step explanation:
3x and 3y are not "like terms," despite having the same coefficient.
Like terms have the same variable. For example, 3x and 2x are like terms, so
3x+2x = 5x
10 x 200 is 2000
therefore there are 200 tens .
In a scientific notation, it would be: 1.5 × 10⁻⁸
In short, Your Answer would be 1.5 × 10⁻⁸
Hope this helps!
Answer:
Average speed is distance/time. You could say, 12/6 = 2 miles per second and say that’s the answer, but we relate to mph so much better. Since there are 60 x 60 = 3600 sec in an hour, that same speed is:
2 x 3600 = 7,200 mph
No “car” can travel this fast. Some rocket cars have gone about 1/10th this speed.
