Answer:
8 minutes or 480 seconds
Step-by-step explanation:
1 km = 1000 m
100x20=2000
24 x 20 = 480
480/60 = 8
It's asking you to find what the value of x and y. You need to subtract the 6x to the other side of the first equation so you can plug the y value into the second equation.. so the second equation should look like 2x+3(-6x+9)=-5. Then you would distribute the 3 to simply it father. So the equation will be, after that, 2x+-18x+27=-5. Then you combine like terms, so it will be -16x+27=-5. Now you would subtract the 27 to the other side and you will get -16x=-22. Now you divide by -16, to get x=-38. Now you have your x value and you can plug it in to find the y value. I would use the first equation just because it will be less work. So you will set it up like 6(-38)+y=9 . Now you just finish the equation. So it should look like this...
-228+y=9
Y=230
