Q is the midpoint of PR. PQ equals 6X -7 and QR equals 5X plus one. Final length of PR.
1 answer:
Answer:
PR = 82
Step-by-step explanation:
Since Q is the midpoint of PR, then
PQ = QR, that is
6x - 7 = 5x + 1 ( subtract 5x from both sides )
x - 7 = 1 ( add 7 to both sides )
x = 8
Thus
PR = PQ + QR = 6x - 7 + 5x + 1 = 11x - 6
Hence
PR = 11(8) - 6 = 88 - 6 = 82

12 miles if you are walking 3 miles every hour then after 4 hours you would have walked 12 miles because 3 milesx4 hours=12
Answer:
Step-by-step explanation:
let the speed of Landon=x
speed of Eduardo=x+9
5x+5(x+9)=135
divide by 5
x+x+9=135/5=27
2x+9=27
2x=27-9
2x=18
x=18/2=9
speed of Landon=9 mph
speed of Eduardo=9+9=18 mph
Answer:
9
