What does Draw and shade a figure that represents 100%. Label your 100%. Then describe the figure in words.

enot [183]

<span><span>In most statistical models to represent easy percentages, circle is mostly preferred. It is purposefully designed or rather allotted for functions that included 100%. A pie chart in technical terms. Imagine an uneaten cake would represent a 100%. </span></span>In most case scenarios, when you eat one slice of the cake. You take a portion that decreases it 100% or a whole presentation, for instance you took 25% slice of cake, what’s left will be 75% and then when you put back again, the 25% slice will present the whole 100%. In words, 25% slice of a cake you take, what’s left will just a portion 75% and unless you put it back it will be whole again.

Four more than the quotient of a number and 3 is 9

barxatty [35]

The algebraic expression of "Four more than the quotient of a number and 3 is 9" is $\frac{x}{3}+4=9$

The value of x=15

Step-by-step explanation:

We need to express "Four more than the quotient of a number and 3 is 9" as algebraic expression.

Let the number = x

Solving:

quotient of a number and 3: $\frac{x}{3}$

Four more than the quotient of a number and 3: $\frac{x}{3}+4$

Four more than the quotient of a number and 3 is 9: $\frac{x}{3}+4=9$

Now, finding value of x:

$\frac{x}{3}+4=9\\Adding\,\,-4\,\,on\,\,both\,\,sides:\\\frac{x}{3}+4-4=9-4\\\frac{x}{3}=5\\Multiply\,\,both\,\,sides\,\,by\,\,3:\\x=5*3\\x=15$

So, value of x = 15

If the following system of equations was written as a matrix equation in the form AX = C, and matrix A was expressed in the form

IrinaVladis [17]

Answer: a-b+c+d =4

Step-by-step explanation:

The given system of equation is

$2x+8y=7\\4x-2y=9$

from this we have the following matrices

$A_1 =\begin{bmatrix}\\2 &8 \\ \\4&2 \\\end{bmatrix}\ ,X=\begin{bmatrix}\\x\\ \\y\\\end{bmatrix}\text{and}\ C=\begin{bmatrix}\\7\\ \\9\\\end{bmatrix}$
