Answer:
There is no solution to the equation.
Step-by-step explanation:
In order to solve the system by substitution, we need to solve the second equation for x.
x - 2y = -8
x = 2y - 8
Now that we have that, we can put that in for x in the other equation and solve for y.
3x - 6y = -12
3(2y - 8) - 6y = -12
6y - 16 - 6y = -12
-16 = -12
No solution

Answer:
4.03cm
Step-by-step explanation:
Note that the diameter of the circumscribed circle to the right triangle is the hypotenuse of the triangle.
To get the diameter, we will use the pythagoras theorem as shown;
d² = 7² + 4²
d² = 49 + 16
d² = 65
d = √65
d = 8.0622577
Since radius = d/2
radius = 8.0622577/2
radius = 4.0311288
Hence the radius of the circumscribed circle to the nearest hundredth is 4.03cm
<span>5000 meters. The prefix kilo- denotes multiplication of 1000. Using this knowledge, a kilometer can be translated to 1000 meters.
The units also each have a shorthanded symbol, kilometer is km and meter is m.
1 km = 1000m
Using this, we can rewrite this equation to fit our problem
5 km = ?m
Substitute in meters for kilometers.
5 (1000m) = 5000m
Giving us the correct answer of 5000 meters.</span>
