The value of x would be 5 for the model 2x+4.

Rearrange unknown terms to the left side of the equation,
$= > 2x-3x = -1 - 4$

Combine like terms $= -x = -1-4$

By calculating the sum or difference : -x = -5

Lets divide both sides of the equation by the resulting coefficient 5
So x = 5

SpyIntel [72]

Mathematics and science go hand in hand. The branches of science which include: Physics, astronomy, chemistry, biology, etc. In all these fields you will find that you will have to use the mathematical principles and formulae to solve the numerical problems. So, science needs maths but maths does not need science.

Find the missing values of the variables. The diagram is not to scale. (Image attached below)thank you ! :)

aniked [119]

Answer:

$\begin{gathered} x=\text{ 99}\degree \\ y\text{ = 64}\degree \end{gathered}$

Explanation:

Here, we want to get the value of x and y

From the given image, the angle y and 116 lie on a straight line

The sum of the angles on a straight line is 180 degrees

Thus:

$\begin{gathered} 116\text{ + y = 180} \\ y\text{ =180-116} \\ y\text{ = 64}\degree \end{gathered}$

The sum of the internal angles of a polygon can be calculated by the formula:

$180(n-2)$

where n is the number of sides the polygon has

In the case of the given question, n is 4

Substituting the value of n, we have it that:

$180(4-2)\text{ = 360 degrees}$

To get the value of x:

$\begin{gathered} x\text{ + y + 125 + 72 = 360} \\ But\text{ from above , y = 64}\degree \\ Substituting\text{ this:} \\ x\text{ + 64 + 125 + 72 = 360} \\ x\text{ = 360-125-64-72} \\ x\text{ = 99 } \end{gathered}$
