Answer:

Q2 2010

Step-by-step explanation:

Let the number of quarters = x

Samsung increases by 6 each quarter.

Apple decreases by 1 each quarter.

Samsung

L = a + (x - 1)*6

a = 1

L = 1 + (x - 1)*6

Apple

L = a - (x - 1)*1

a = 53

L = 53 - (x - 1)*1

Now the problem is how many quarters go by until they meet?

1 + (x - 1)*6 = 53 - (x - 1) Remove the brackets

1 + 6x - 6 = 53 - x + 1 Combine like terms on both sides.

-5 + 6x = 54 - x Add 5 to both sides

6x = 59 - x Add x to both sides

7x = 59

x = 59/7 = 8 3/7

So sometime in the 8th quarter from zero they will be equal. At the end of the quarter, Samsung will be greater than Apple

So the answer should be 4 quarters from Q2 2009 or Q2 2010

Which expression is equivalent to...

olga_2 [115]

Answer:

$8m^5$

Step-by-step explanation:

Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)

This gives us the fraction: $\frac{24m^7}{3m^2}$

We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction: $\frac{24 * m * m * m * m * m * m * m}{3 * m * m}$

Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:

$\frac{24 * m * m * m * m * m}{3}$ which can be simplified in exponent form as: $\frac{24m^5}{3}$ , now all we have to do is divide the 24 by the 3, to get 8

This gives us the answer: $8m^5$
