 3x + 4y = 5
<u>-5x - 4y = -11</u>
       -2x = -6
       -<u>2x</u> = <u>-6</u>
        -2     -2
          x = 3
3(3) + 4y = 5
    9 + 4y = 5
<u>   -9          -9</u>
         4y = -4
         <u>4y</u> = <u>-4</u>
          4      4
           y = -1
     (x, y) = (3, -1)

An athlete ran 200 meters in 19.19 seconds. Suppose that he ran the first half of that race (around a curve) in 10.75 seconds. H
SOVA2 [1]

The time needed to run the second half of the race is 8.44 s

Step-by-step explanation:

The total distance covered by the athlete during the race is

d = 200 m

And the total time taken to cover this distance is

T = 19.19 s

We also know that the time the athlete needs to cover the first half of the race is

t_1 = 10.75 s

Also, we know that

T=t_1 + t_2

where t_2 is the time the athlete takes to cover the second half of the race.

Re-arranging this equation and susbtituting the values, we find the value of t2:

t_2 = T-t_1 = 19.19-10.75=8.44 s
