What is the value of x?

Alexxandr [17]

These are vertical angles, so they are equal in measurements.

First, simplify [2(x + 10)]

Distribute 2 to all terms within the parenthesis

2(x + 10) = 2x + 20

Next, place both expressions equal to each other

2x + 20 = 3x - 30

Solve for x. Isolate the variable. Subtract 3x and 20 from both sides

2x (-3x) + 20 (-20) = 3x (-3x) - 30 (-20)

2x - 3x = -30 - 20

Simplify

-x = -50

Isolate the x. Divide -1 from both sides

-x/-1 = -50/-1

x = 50

50 is your answer for x

hope this helps

olya-2409 [2.1K]

ANSWER:

52 shrubs

STEP-BY-STEP EXPLANATION:

We know the number of trees planted in a given area, so to calculate the number of total trees, we must calculate the area of the entire figure and thus calculate by means of a proportion

We calculate the total area if we divide the figure in two, as follows:

The area of zone A, which is a rectangle, is calculated as follows:

$\begin{gathered} A_A=b\cdot h \\ A_A=50\cdot20 \\ A_A=1000 \end{gathered}$

The area of zone B, which is a triangle, is calculated as follows:

$A_B=\frac{b\cdot h}{2}$

To calculate the value of the height of the triangle, we apply the Pythagorean theorem on the right triangle that is formed:

Where the hypotenuse is 25 meters and the other leg is 15 meters, just like this:

$\begin{gathered} h^2=a^2+b^2 \\ 25^2=15^2+b^2 \\ b=\sqrt[]{25^2-15^2} \\ b=\sqrt[]{400} \\ b=20 \\ \text{therefore the height is 20 meters, replacing:} \\ A_B=\frac{30\cdot20}{2} \\ A_B=300 \end{gathered}$

Now, the total area would be the sum of both areas:

$\begin{gathered} A_T=1000+300 \\ A_T=1300 \end{gathered}$

Which means that if in an area of 400 square meters (20 * 20) they can plant 16 shrubs, in an area of 1300 square meters they would be:

$\begin{gathered} \frac{16}{400}=\frac{x}{1300} \\ \text{ solving for x} \\ x=\frac{16\cdot1300}{400} \\ x=52 \end{gathered}$

In other words, a total of 52 shrubs can be raised throughout the region.
