Diego and Anya live 72 miles apart. They both meet at
their favorite restaurant, which is (16x – 3) miles from
Diego's house and (5x + 2) miles from Anya's house.
Diego argues that in a straight line distance, the restaurant
is halfway between his house and Anya's house. Is Diego
right? Justify your reasoning.

Answer:

The restaurant is not at half way

Step-by-step explanation:

Given

[tex]Total\ Distance = 72[/tex]

[tex]Diego = 16x - 3[/tex]

[tex]Anya = 5x + 2[/tex]

Required

Accept or reject Diego's claim

To do that, we need to determine the value of x by:

Diego + Anya =Total Distance

Substitute values for each parameter

[tex]16x - 3 + 5x + 2 = 72[/tex]

Collect Like Terms

[tex]16x + 5x = 72 + 3 - 2[/tex]

[tex]21x = 73[/tex]

Divide both sides by 21

[tex]x = \frac{73}{21}[/tex]

Substitute the value of x in Diego and Anya's distance

[tex]Diego = 16x - 3[/tex]

[tex]Diego = 16 * \frac{73}{21} - 3[/tex]

[tex]Diego = \frac{1168}{21} - 3[/tex]

[tex]Diego = \frac{1168 - 63}{21}[/tex]

[tex]Diego = \frac{1105}{21}[/tex]

[tex]Diego = 52\frac{13}{21}[/tex]

[tex]Anya = 5x + 2[/tex]

[tex]Anya = 5 * \frac{73}{21} + 2[/tex]

[tex]Anya = \frac{365}{21} + 2[/tex]

[tex]Anya = \frac{365 + 42}{21}[/tex]

[tex]Anya = \frac{407}{21}[/tex]

[tex]Anya = 19\frac{8}{21}[/tex]

Since, both distances are not equal,

Then Diego's claim is false and incorrect
