The option (B) 2,-2 is correct because the number satisfy the provided expression.

<h3>What is an arithmetic operation?</h3>

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have a number bank shown in the picture.

The problem given:

7 - __ = 7 + __

A. 3,-4

Checking for the above option:

7 - 3 = 7 - 4

4 = 3 (false)

B. 2,-2

Checking for the above option:

7 - 2 = 7 - 2

5 = 5 (true)

O C. 1;-4

Checking for the above option:

7 - 1 = 7 - 4

6 = 3 (false)

D. 2; 3

Checking for the above option:

7 - 2 = 7 + 3

5 = 10 (false)

Thus, the option (B) 2,-2 is correct because the number satisfy the provided expression.

WILL GIVE BRAINLY Find the perimeter of the figure below, in meters.

yan [13]

Answer:

$147.6\:\mathrm$

Step-by-step explanation:

The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.

Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:

$9.8+9.8+11.7+9.8+21.5+21+11.7+9.8+31.3+11.2=\boxed{147.6\:\mathrm{m}}$

Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.

A road has a 10% grade, meaning increasing 1 unit of rise to every 10 units of run.

finlep [7]

Answer:

Part a) The elevation of the road is $6\°$

Part b) The rise is $0.2\ km$

Step-by-step explanation:

Part a) What is the elevation of the road to the nearest degree?

Let

y-----> the rise of the road ( vertical distance)

x ----> the run of the road (horizontal distance)

we have

y/x=1/10

we know that

The ratio y/x is equal to the tangent of the angle of the elevation of the road

Let

$\theta$ ----> angle of the elevation of the road

$tan(\theta)=y/x$

$tan(\theta)=1/10$

$\theta=arctan(1/10)=6\°$

Part b) If the road is two km long, how much does it rise?

using proportion

$1/10=y/2$

$y=2/10=0.2\ km$
