Problem

$\frac{5x}{x+7} + \frac{7}{x}$

Work

$\frac{5x(x)+7(x+7)}{x(x+7)}$
$\frac{5x^{2} +7x+49}{x(x+7)}$
The student's mistake was that instead of taking x(x + 7) as the LCM (Least Common Multiple), he took x + 7, which is not possible in this case

Solution

$\frac{5x^{2} +7x+49}{x(x+7)}$

(3x²+3x+5)+(7x²-9x=8)=10x²-12x=13

The value of x is equal to -5/6

To solve this question, we have to add two polynomials together. The polynomials are;

$3x^2+3x+5$
$7x^2-9x=8$

<h3>Addition of Polynomials</h3>

This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.

In this given question, let's add the polynomials together.

$(3x^2+3x+5) + (7x^2-9x = 8\)\\3x^2 + 7x^2 + 3x-9x+5-8 =10x^2-6x-3$

Now, let's equate this with the last polynomial given

$10x^2-6x-3=10x^2-12x-13\\10x^2-10x^2-6x+12x-3+13\\0+12x+10\\12x=-10$

Let's solve for x

$12x=-10\\x=-\frac{10}{12}\\x = -\frac{5}{6}$

The value of x is equal to -5/6

Answer:

45/2

Step-by-step explanation:

ashjasdhkjasdha hello there

There are two people and there are 45 minutes to shoot the ball. As both people shoot for the exact same time, you have to divide 45 by 2 to split the time into two equal halves. Thus, the answer is 45 divided by 2, or just 45/2.

gavmur [86]

Answer:

Step-by-step explanation:

An eccentric philanthropist undertakes to give away $100,000. He is eccentric because he insists that each of his gifts be a number of dollars that is a power of two, and he will give no more than one gift of any amount. How does he distribute the money?

To solve this problem, we will simply write 1,00,000 in base 2.

2^17 gives 131072, 2^16 gives 65536.

So, the first gift is 65536, we then need to repeat this process for 34,464 ((100,000-65536 = 34,464), to get all gifts in succession.

6 gifts in all: one each of $32, $128, $512, $1024, $32768, and $65536.
