Okay so the three in 6300 is 10 times bigger than the three and a 530 why because the three in six hundred thirty is in the hundredths place and the three in 530 is in the tenths place meaning that the 3 in 6300 is 10 times bigger than the one in 530. what do I mean by 10 times bigger? consider this 3 * 10 equals 30 or if you Annex a 0 at the end it would be 300 as in 6 thousand three hundred
Answer:
Jean is 9 and Tom is 15.
Step-by-step explanation:
3 years ago, Tom was 12 and Jean was 6, hence Tom was twice as old as Jean.
Since that was their age 3 years ago, they are currently 15 (Tom) and 9 (Jean).
Add 2 years to each of these ages, you get 17 and 11.
17 + 11 = 28
The first two are alike because you have to add 3 to each side for everything to come out even.
<u><em>Answer:</em></u>
<u>The simplest form would be:</u>
8c² - 1.5d
<u><em>Explanation:</em></u>
To simplify an expression, we need to <u>gather the like terms</u>.
Like terms are the ones having the same variable raised to the same power
<u>In the given expression:</u>
6c² + 2.5d - d + 2c² - 3d
We have terms having c² and terms having d.
<u>Therefore, we would gather them as follows:</u>
6c² + 2.5d - d + 2c² - 3d
(6+2)c² + (2.5-1-3)d
8c² - 1.5d ......................> This is the simplest form
Hope this helps :)
I believe the answer is A. because the theory of continental drift and sea-floor spreading causes new rock to form and creates the old rock .. older
