Answer:
<em>The actual distance between the cities is 1,200 Km</em>
Step-by-step explanation:
<u>Scaling
</u>
Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
We are given the scale on a map as 1:20,000,000.
Two cities are 6 cm on the map. The actual distance is obtained by multiplying:
6 * 20,000,000 = 120,000,000 cm
Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km
The actual distance between the cities is 1,200 Km
Answer:
(-2,8)
Step-by-step explanation:
To solve by substitution, first isolate a variable in one of the equations. Then, substitute the value of the variable from that equation into the other equation, giving either the x or y value of the solution. Finally, substitute that answer back into one of the two equations, finding the other missing value.
1) For both of the equations, the variable y has already been solved for. So, we can choose to substitute whatever y equals in one equation for the y in the other equation. Any choice is fine - I chose to substitute -4x for the y in y = 3x + 14.
2) Now that x has been solved for, substitute the value for the x in one of the equations. Any choice is fine here, too - I chose to substitute -2 in y = -4x:
3) Both the x and y value of the solution has been solved for. x = -2 and y = 8. Therefore, the solution is (-2,8).
