x = 1.314286

~~~~~~~~~~

0.5(5-7x) = 8 - 4.1 - 6

0.5(5-7x)=3.9-6

0.5(5-7x) = -2.1

5-7x= - 2.1/0.5

5-7x=-4.2

-7x = -4.2 - 5

-7x=-4.2-5

-7x=-9.2

x= - 9.2/-7

x = 1.314286

Given α and β are Supplementary. Show the necessary steps.
user100 [1]

Answer:

\alpha = 108\degree, \: \beta = 72\degree

Step-by-step explanation:

α and β are Supplementary (given)

\therefore \alpha + \beta = 180\degree.... (1)

It is given that:

\alpha= \frac{3}{2} \beta

Plugging the value of α in equation (1), we find:

\frac{3}{2} \beta + \beta = 180\degree

\therefore  \frac{3+2}{2} \beta = 180\degree

\therefore  \frac{5}{2} \beta = 180\degree

\therefore   \beta = 180\degree\times \frac{2}{5}

\therefore   \beta = 72\degree

\implies   \alpha= \frac{3}{2} \times 72\degree= 108\degree

So,

\alpha = 108\degree, \: \beta = 72\degree

(Multiplying and Dividing with Scientific Notation LC)
Assoli18 [71]

The product in scientific notation is 8*10^2

<h3>How to multiply and divide in scientific notation?</h3>

Here we want to find the product between 4*10^6 and 2*10^6, and write that in scientific notation.

First, we can solve the direct product:

(4*10^6)*(2*10^6) = (4*2)*(10^6*10^6)

Here we used the fact that we can multiply in any order we want.

Now we will use the property:

a^n*a^n = a^{n + m}

(4*2)*(10^6*10^6) = 8*10^{6 + 6} = 8*10^12

The correct option is the second one, counting from the top.
