Answer:

9 sides

Step-by-step explanation:

7y + 2y = 180

9y = 180

The units of the subway map below are in miles. Suppose the routes between stations are straight. Station​ G, not shown on the​
slega [8]

Answer:

8.60 miles

Step-by-step explanation:

If S=station​ G, not shown on the​ map, is 5 miles east and 7 miles south of Station A, the approximate distance between Station E and Station G when traveling by​ subway will be gotten using the Pythagoras theorem.

EG² = 5²+7²

EG² = 25+49

EG² = 74

EG = √74

EG = 8.60 miles

<em>Hence the approximate distance between Station E and Station G when traveling by​ subway is 8.60miles</em>

PLEASE HELP ASAP!!! <br> Thank you!
Marrrta [24]
The answer is 380 cm. I first found the area of the triangles (14x10x0.5), then I multiplied that by four (because there are 4 triangles total) getting 280. Then I added the area of the base (10x10=100) to 280. Good luck my bud

The system crosses at the point (3, 4). How many solutions will the system have?
vagabundo [1.1K]
For this case suppose that we have a linear system of equations of the form:
 ax + by = c
 dx + ey = f
 The solution of the system is an ordered pair of the form:
 (x, y)
 That is, both lines intersect at a point.
 The point of intersection in this case is:
 (3, 4)
 Therefore, the system has one solution.
 Answer
 
the system will have:
 
one solution
