Answer:
x = -4/9
Step-by-step explanation:
-3(4x − 2) = 6x + 14
Distribute
-12x+6 = 6x+14
Add 12x to each side
-12x+6+12x = 6x+14+12x
6 = 18x+14
Subtract 14 from each side
6-14 = 18x
-8 =14x
Divide each side by 14
-8/14 = 14x/14
-4/9 = x
It would have taken you 5:30 for each mile. 55/10 is 5.5 thats 5 and a half, half a minute is 30 seconds. so 5 minutes and 30 seconds
you have to convert meters to centi-meters first;
800m = 80000 cm & 154m = 15400 cm
Now, Substitute that in your original equation;
80035 cm - 15449
64586 cm
