Answer:

x=-3

Step-by-step explanation:

Given:

4\frac{3}{10}-(2\frac{2}{5}x+5\frac{1}{2})=\frac{1}{2}(-3\frac{3}{5}x+1\frac{1}{5})

Distribute to remove parentheses:

4\frac{3}{10}-2\frac{2}{5}x-5\frac{1}{2}=-\frac{18}{10}x+\frac{6}{10}

For simplification and clarity, reduce all mixed numbers to simplified common fractions:

\frac{43}{10}-\frac{12}{5}x-\frac{11}{2}=-\frac{9}{5}x+\frac{3}{5}

Combine like terms:

-\frac{12}{5}x-\frac{6}{5}=-\frac{9}{5}x+\frac{3}{5}

Add 6/5 to both sides, then add 9/5x to both sides:

-\frac{3}{5}x=\frac{9}{5}

Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):

x=\frac{9}{5}\cdot -\frac{5}{3}, \\x=\frac{-9}{3},\\x=\boxed{-3}

Ursula bought 9 dozen rolls of first aid tape for the health office. The rolls were divide equally into 4 boxes.
Vilka [71]
A dozen is equal to 12 so you have to do 12 x 9 = 108.

108 ÷ 4 = 27 so there was 27 rolls in each box.

Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on
stiv31 [10]

Answer:

When we have a quadratic equation:

a*x^2 + b*x + c = 0

There is something called the determinant, and this is:

D = b^2 - 4*a*c

If D < 0, then the we will have complex solutions.

In our case, we have

5*x^2 - 10*x + c = 0

Then the determinant is:

D = (-10)^2 - 4*5*c = 100 - 4*5*c

And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:

D = 0 = 100 - 4*5*c

    4*5*c = 100  

       20*c = 100

            c = 100/20 = 5

As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.

This means that c must be larger than 5 if we want to have complex solutions,

c > 5.

I can not represent this in your number line, but this would be represented with a white dot in the five, that extends infinitely to the right, something like the image below:
