The whiteboards she bought cost $35, and she spent a total of $51.20, subtract to find out the total amount she spent on posters:

\sf 51.20-35=16.2

So she spent a total of $16.20 on posters, now divide by the amount one poster costs to find out how many posters she bought.

\sf 16.2\div 5.4=\boxed{\sf 3}

So she bought 3 posters.

if you practice a musical instrument each day for 2/3 of an hour how many hours of practice would you get in each week?
RideAnS [48]
In order to find the answer of the given problem above, we need to make the solution below:
Given: 2/3 of an hour = practice each day
           2/3 of an hour is equivalent to 40 minutes
And per week, there are 7 days. So we will multiply 40 minutes by 7, and the result is 280 minutes. Since there are 60 minutes in an hour, we divide 280 by 60 and we get 4.67 hours. Therefore, each week, you would get 4.67 hours of practice on playing a  musical instrument.

factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)
Mila [183]

Consider the polynomial 4x^5 - 20x^4 - 36x^3. It has three terms and their greatest common factor is 4x^3.

Since

4x^5=4x^3\cdot x^2,\\20x^4=4x^3\cdot 5x,\\36x^3=4x^3\cdot 9,

then

4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9) (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.

Consider the trinomial 6x2 + 13x + 6.
attashe74 [19]
In the given expression 6X² + 13X +6, we can easily identify the values of a, b and c. These values are a=6, b=13 and c=6
For the value of "ac", we have:
ac=6*6
ac=36
For a sum of b are 4, we have
ac+b=36+13=49
Therefore, the answer for the last question "The two numbers that have a product of ac and a sum of b are 4 and 9".
