What is x for negative 8(x plus 2 ) plus 5x equals negative 4

Mathematics
1 answer:
Anarel [89]3 years ago
4 0
 - 8 ( x + 2 )  + 5x  = - 4

Start by distributing.....

- 8 x - 16 + 5x = - 4

Combine like terms.....

     - 3 x - 16 = - 4

Add 16 to both sides.....

         - 3x = 12 

 Divide both sides by -3 to get x by its self.....

           x = - 4 is the answer

Find the sum of 10 x 2 + 7 x + 6 10x 2 +7x+6 and 6 x + 5 6x+5.
dusya [7]

The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11

<h3>Sum of expressions</h3>

Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns

Given the following expression

10x^2 +7x+6 and 6x + 5

We are to take the sum of both expression to have:

f(x) = 10x^2 +7x+6 + 6x + 5

Collect the like terms

f(x) = 10x^2 + 7x + 6x + 6 + 5

f(x) = 10x^2 + 13x + 11

Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11

Find the ratio of the volume of one sphere to the volume of the right cylinder
yarga [219]

Answer:

B


Step-by-step explanation:

<em>Let r be the radius of one sphere.</em>

  • Volume of sphere is V=\frac{4}{3}\pi r^3

Since radius is r,  the height of the cylinder will be 4r

Also, the cylinder has the same radius as the sphere: r


  • Volume of Cylinder is V=\pi r^2 h

Plugging in the values we get: V=\pi (r)^{2}(4r)=4\pi r^3


<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:

\frac{\frac{4}{3}\pi r^3}{4\pi r^3}=\frac{\frac{4}{3}}{4}=\frac{4}{3}*\frac{1}{4}=\frac{1}{3}

The ratio is 1:3

Answer choice B is right.

You have $1,998.00 on a credit card with a 14.5% APR. You miss your minimum payment the first month and there is a late fee of $
Minchanka [31]
There are 2 parts to this question.  1. One would be to calculate the interest based on your balance and 2. then to add the late fee.  Use the formula i = prt to calculate your simple interest. <em>i</em> represents the interest you will pay, <em>p</em> stands for the principal (balance on your credit card), and <em>t</em> stands for the period of time (related to a period of a year/annual percentage rate).  The $1998 balance times 0.145 times 1/12 gives the interest amount of $24.14.  So, $1998 + $24.14 + $37 = $2059.14 balance.
