Mathematics

Answer:

(-1, 3)

Step-by-step explanation:

replace the occurrences of y in the equation

(x + y = 2) with x + 4

x + x + 4 = 2

2x + 4 = 2

solving for x in the first equation

2x = 2 - 4

2x = -2

2x/2 = -2/2

x = -1

replacing all occurrences of x in y = x + 4 with -1

y = (-1) + 4

y = 3

therefore the pairs are (-1, 3)

Hope it helps!

In a race from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X. Sa
svlad2 [7]

Answer:

Sandy will finish the race first.

Step-by-step explanation:

Let D be the total one sided distance in miles, ( between X and Y ),

We know that,

Speed =\frac{Distance}{Time}

\implies Time =\frac{Distance}{Speed}

Since, from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X.

So, the total time taken by Jack = \frac{D}{30}+\frac{D}{10}

=\frac{D+3D}{30}

=\frac{4D}{30}

=0.1333D

Also, Sandy averages 20 miles per hour in both directions,

So, the total time taken by Sandy = \frac{D}{20}+\frac{D}{20}

=\frac{D+D}{20}

=\frac{2D}{20}

=\frac{D}{10}

=0.10D

∵ 0.133D > 0.10D

Hence, Sandy will finish the race first.
