model train tracks are set up in three connecting circles. length of tracks in each circle is 210 meters. the red and the blue t

rain start at complete opposite sides of the course. each train only uses two circles, thus their whole journey can be described as a number eight. the red train starts going clockwise with a speed of 20 meters per minute, the blue train starts going counter-clockwise wit

Base on the said question, and the given problem above, the duration of the train that it would take for the two trains to collide, base on my research and further computation, is 9 minutes. I hope you are satisfied with my answer and feel free to ask for more if you have questions

10 POINTS Which expressions are equal to 6^3 x 2^6/2^3?
Kaylis [27]
When dividing, exponential powers are subtracted. When multiplying, power are added the base remains the same if the two bases are the same number. If they are different, the bases are multiplied and the same power is simply kept. With this in mind, let us solve this question!

6^3 × 2^6 / 2^3 ----- Multiplication or division can be done first. I do division because it's easier that way. 6-3 = 3

6^3 * 2^3 ------ Multiply bases and keep the power.

B.) 12^3

Hope this helps!

How do you factor 35x^2+26-16? Show work please.
Sedbober [7]

well, first off, we do a quick prime factoring of the leading term's coefficient, 35, and the constant, 16.

35 = 5*7

16 = 2*2*2*2

and the rest is just a mix and match.

what combination from the factors of 35 and the factors of 16, can provide a product whose sum is the middle term 26?  well, without further adieu.


we can try 5*2*2  + 7*2*2, and that's 20 and 28, ok, 28 - 20 is 8, so that won't work.

another can be 5*2*7  and 2*2, that's 70 and 4, 70 - 4 is 56, that won't work either.

5*2*2*2 and 7*2, that's 40 and 14, hmmm 40 - 14 = 26!!! holly guacamole!

so then,


\bf 35x^2+26x-16\implies (5x-\stackrel{\stackrel{2}{\downarrow }}{2})(7x+\stackrel{\stackrel{2\cdot 2\cdot 2}{\downarrow }}{8})

What is the answer when you round 522 254 to the nearest 10​
DiKsa [7]

Answer:

522250

How to round to the nearest tenth:

Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit. If it is 4 or lower, the tenths digit remains the same.

For example, 3.58 can be rounded to 3.6 because the hundredths place digit, 8 is greater than or equal to 5.

3.32 would be rounded to 3.3, because the hundredths place digit, 2, is less than 5.

Can you guys give me the steps for this plus the answer?
Alex_Xolod [135]

Answer:

x = -9

Step-by-step explanation:

First rearrange the terms.

-6x - 6x +3 = 111

Add like terms

-12x + 3 = 111

Subtract 3 from both sides

-12x = 108

Divide -12 on both sides

x = -9
