Answer:

13/15

Step-by-step explanation:

We were told in the question that:

Javier sale de su casa con $125 y gasta 3/5 en el cine y 4/15 en palomitas.

La fracción que representa la fracción del dinero que ha gastado se calcula como:

3/5 + 4/15

Mínimo común múltiplo = 15

= (3 × 3) + (4 × 1) / 15

= 9 + 4/15

= 13/15

Por tanto, la fracción del dinero que ha gastado es 13/15

You are supposed to distribute to only one term (the first).

Tom [10]

Answer:

true

Step-by-step explanation:

There is no distribution (unless you count substitution) in the second set of terms.

Edit: I think I get what your question is now. You are supposed to distribute to every term inside the parenthesis (false)

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: $8m^5$
