Answer:

x = -4

Step-by-step explanation:

x + 4 = -x - 4

adding both side with x

x + x + 4 = x - x - 4

2x + 4 = -4

give both side (-4)

2x + 4 - 4 = -4 - 4

2x = -8

x = -8/2 = -4

The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?
Alexxx [7]

Answer:

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance between two cities = 87 kilometers

Scale of the map = 1:600,000

2.  What is the distance between them on a map with that scale?

For finding out the answer to this question, we need to:

A. Convert 87 kilometers to centimeters, that is the average distance measurement of the maps, this way:

87 kilometers = 87,000 meters (multiplying by 10³)

87,000 meters = 8'700,000 centimeters (multiplying by 10²)

B. Now we divide the measurement in centimeters by the scale, this way:

8'700,000/600,000 = 14.5

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount? $50(0.20) $50(1 – $50)(0.2
lina2011 [118]
<span>The correct equation is $50(0.80). The discount is 20% or 0.20, so we multiply the original price by 1-(discount), which is 1-0.2, so we multiply by 0.80.</span>
