The value of x in the equation is 26. 087

<h3>What are algebraic expressions?</h3>

Algebraic expressions are defined as expressions made up of terms, constants, coefficients, factors and variables.

They may also include certain mathematical or arithmetic operations which includes;

Bracket
Division
Addition
Subtraction
Parentheses
Multiplication and so on

Given the equation;

(0.020) (0.030) / (0.10)x = 2.3 × 10-4

We can simply the equation following the steps;

expand the brackets, we have;

6× 10^-4/ 0.10x = 2.3 × 10^-4

Now, cross multiply

0.10x × 2.3 × 10^-4 = 6× 10^-4

Divide both sides by 2.3 × 10^-4

0. 10x = 6× 10^-4/2.3 × 10^-4

Find the quotient

0. 10x = 2. 608

Let's make the variable 'x' by dividing both sides by it's coefficient

0. 10x/0.10 = 2. 608/0. 10

x = 26. 087

Hence, the value is 26. 087

NEED QUICKLY <br> GEOMETRY 20 POINTS

sp2606 [1]

Answer:

10.24 in²

Step-by-step explanation:

First we need to know how to find the area of a rectangle, which is base * height.

We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.

To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.

We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!

What two number multiply to negative 20 and add to 19

OLEGan [10]

$x;\ y-the\ numbers\\\\ \left\{\begin{array}{ccc}xy=-20\\x+y=19&\Rightarrow&x=19-y\end{array}\right\\\\subtitute\ to\ first\ equation:\\\\(19-y)y=-20\\19y-y^2+20=0\\-y^2+19y+20=0\ \ \ |change\ signs\\y^2-19y-20=0\\y^2-20y+y-20=0\\y(y-20)+1(y-20)+0\\(y-20)(y+1)=0\iff y-20=0\ or\ y+1=0\\\\y=20\ or\ y=-1$

$x=19-y\\\\for\ y=20\Rightarrow x=19-20=-1\\\\for\ y=-1\Rightarrow x=19-(-1)=20\\\\Answer:\boxed{\boxed{20\ and\ -1}}$

Identify and explain the causes of WW1

saveliy_v [14]

The direct cause of WWI was the assassination of Archduke Franz Ferdinand at Sarajevo on 28 June 1914. However historians feel that a number of factors contributed to the rivalry between the Great powers that allowed war on such a wide-scale to break out.

which of the following correlation coefficients is indicative of the strongest relationship between the two variables

VladimirAG [237]

The strongest linear relationship of correlation coefficient is a -1 or 1.

According to the statement

we have given that the cases and the out of these we have to ensure that which case show the correlation coefficients is indicative of the strongest relationship between the two variables

So, For this purpose

The relationship of correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

And according to the given cases

The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.

The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

So, The strongest linear relationship of correlation coefficient is a -1 or 1.
