Which statements are true about the ordered pair (−1, 5) and the system of equations? {x+y=4 {x−y=−6 select each correct answer. the ordered pair (−1, 5) is a solution to the first equation because it makes the first equation true. the ordered pair (−1, 5) is a solution to the second equation because it makes the second equation true. the ordered pair (−1, 5) is not a solution to the system because it makes at least one of the equations false. the ordered pair (−1, 5) is a solution to the system because it makes both

The answer is A) The ordered pair (−1, 5) is a solution to the first equation because it makes the first equation true.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
