4x+15=6x-5 solve for x

hram777 [196]

Answer:

x = 10

Step-by-step explanation:

Breaking down the equation

$4x+15=6x-5\\4x+15-15=6x-5-15\\4x=6x-20\\4x-6x=6x-20-6x\\-2x=-20\\\frac{-2x}{-2}=\frac{-20}{-2}$

Simplification

$\frac{-2x}{-2}\\=\frac{2x}{2} (\frac{-x}{-y} = \frac{x}{y})\\\frac{2}{2} = 1 = x\\\\\frac{-20}{-2}\\=\frac{20}{2}\\\frac{20}{2}\\=10$

the angle of elevation from the tip of the shadow to the top of the tree is 36 degrees. find the distance from the top of the tr

Bas_tet [7]

In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:

sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse

Answer:

$5$

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let:

$P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)$

The distance between these points is equal to:

$d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}$
