3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3
3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3
solution is (8/3, 19/3)
So of you set it equal to each other
150m+3m = 9m
-3m = -3m
you get 150m=6m
and you divide by 6 on each side so it comes out to 25 minutes... I think...
1/3 mile x 9 times = 3
They both are 9/3 simplifies to 3
Answer:
10 hours and 20 minutes
Step-by-step explanation:
3am to 4am is 20 minutes
4am to 2pm is 10 hours
$35 is your answer, just do 25(0.40) which gives you 10 so add that to your original 25+10=35
