Q. Natasha and her two dogs were walking on a perfectly straight road when her two dogs ran away from her in opposite directions. Her beagle is now 425 meters directly to her right, and her labrador is 2051 meters directly to her left.Which 2 of the following expressions represents how far apart the two dogs are?Choose 2 answers:(A) ∣∣425+2051∣∣(B) ∣∣−2051+425∣∣(C) ∣∣−2051−425∣∣
Understand the situation: Understand the situation.Natasha's beagle is 425 meters to her right, and her labrador is 2051 meters to her left. Since they ran in opposite directions, the distance between them is the sum of these two distances.
Convert fractions to common denominator: Convert the fractions to have a common denominator to add them easily.The common denominator for 4 and 20 is 20. Convert (425) to a fraction with a denominator of 20.(425)×(55)=(20125)
Add distances together: Add the distances together.Now that both fractions have the same denominator, add them together.(20125)+(2051)=(20176)
Simplify the fraction: Simplify the fraction.(176/20) can be simplified by dividing both the numerator and the denominator by 4.(176/20)/(4/4)=(44/5)
Convert to mixed number: Convert the simplified fraction to a mixed number.(44/5) is equal to 8 with a remainder of 4, so it can be written as 84/5 or 8.8 meters.
Determine correct expressions: Determine the correct expressions.The distance between the two dogs is the absolute value of the sum of the distances from Natasha to each dog. The correct expressions must add the two distances together.A. ∣∣425+2051∣∣ is correct because it adds the two distances.B. ∣∣−2051+425∣∣ is also correct because it represents the same sum, just starting with the labrador's distance.C. ∣∣−2051−425∣∣ is incorrect because it subtracts the distances, which does not represent the total distance between the two dogs.
