In a race, the-second place finisher crossed the finish line 1 1/3 minutes after the winner. The third-place finisher was 1 3/4
KiRa [710]

Answer:

First Winner take 31.95 minute time to complete race.

Step-by-step explanation:

Since the third winner take 34\frac{2}{3} minutes to complete the race.

Second winner take 1\frac{3}{4} minutes less than Third Winner.

Thus Second winner take 34\frac{2}{3}-1\frac{3}{4}\\  \frac{104}{3}-\frac{7}{4}\\ \frac{395}{12} =32.92 \ minutes

Also, First winner take 1\frac{1}{3} minutes less time.

Thus first winner take time = \frac{395}{12}-1\frac{1}{13}\\ \frac{395}{12}-\frac{14}{13}=31.95 minutes

Someone, please help me fill this out
nadezda [96]

Answer:

Here is the summary:

  • y = 13x+5 satisfies the points (0, 5) and (-2, -21)
  • y = -3x satisfies the points (0, 0), (-5, -15) and (-3, 9)
  • y = x-10 satisfies the points (8, -2)

Step-by-step explanation:

Given the equation

  • y = 13x+5
  • y = -3x
  • y = x-10

The points which satisfy the equation y=13x+5

y = 13x+5

Checking the point (0, 5)

5 = 13(0)+5

5 = 0 + 5

5 = 5

TRUE

Checking the point (-2, -21)

-21 = 13(-2)+5

-21 = -26 + 5

-21 = -21

TRUE

The points which satisfy the equation y=-3x

y = -3x

Checking the point (0, 0)

0 = -3(0)

0 = 0

TRUE

Checking the point (-5, -15)

y = -3x

-15 = -3(-5)

-15 = -15

TRUE

Checking the point (-3, 9)

y = -3x

9 = -3(-3)

9 = 9

TRUE

The points which satisfy the equation y=x-10

y = x-10

Checking (8, -2)

-2 = 8 - 10

-2 = -2

TRUE

Therefore, from the above calculations we conclude the summary:

Here is the summary:

  • y = 13x+5 satisfies the points (0, 5) and (-2, -21)
  • y = -3x satisfies the points (0, 0), (-5, -15) and (-3, 9)
  • y = x-10 satisfies the points (8, -2)
