Answer:
Step-by-step explanation:
Bill + 220
Total is 538 so subtract 220 which gives you 318.
318/2 = 159
159+220 for Bill = 379
Bob has 159
Add 159 + 220 for Bill and 159 for bob = 538
So Bill has 379
and Bob has 159
M.m.c (30, 60, 300)
30, 60, 300|3
10, 20, 100|2
5, 10, 50 |5
1, 2, 10 | ===> 3*2*5 = 30
30 stundents
Answer:
I think its the 1st one, but I'm not sure
(6x+9y=78) - (6x+4y=38) = (5y=40) = y=8
(2x+3(8)=26) = (2x+24=26) = (2x=2) = x=2
Answer: B= -54t +367
N=-50t + 347
so in total would be 5 HOURS
