Solve 5x(m+n) using the distributive property

Genrish500 [490]

Answer: $5xm+5xn$

Step-by-step explanation:

For this exercise it is necessary to remember the following:

1) The Distributive Property states the following:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2) The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

Knowing this, and having the following expression given in the exercise:

$5x(m+n)$

You can apply the Distributive property multiplying $m$ and $n$ , which are inside the parentheses, by $5x$ .

So, you get the following result:

$=(5x)(m)+(5x)(n)=5xm+5xn$

Veronika [31]

Answer:

53.12

Step-by-step explanation:

You can do it 2 ways

1st way

83 multiplied by .33

83 is the amount and .33 is the percent

Now you have the mark downed price, so you subtract that from the original of 83

2nd way

subtract 33 from 100 because the price is 33% off

now multiply 83 by 0.64 because the .64 represents 64%
