60 divide dos by 15 is 4, so it takes 4 minutes for each person to empty it.
25 x 4 = 100, so the answer would be 100 minutes.

Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52

Answer:
6a + (6 x 3) = 60
or
6a + 18 = 60
Step-by-step explanation:
You have 6 students who are assigned an unknown amount of problems. We can write it as 6x. Then each is given 3 more problems, so now we have 6x + (6 x 3). We also know that in all they have 60 problems.
Therefore, the equation is:
6x + 18 = 60
Then just solve
6x + 18 = 60
- 18 -18
6x = 42
x = 7
1° associativity
2° symetrical
3° neutral
