Answer:
A
Step-by-step explanation:
- He spends:
- 30 mins on History
- 60 mins on English
- x mins on math
- so the total time he spends is
- one fourth of this is his math time, since x is math time, then we have
- But we know what totaltime in minutes is so
- or simply:
A plane that has more than one agent
the answer would 1/4 of a gallon
simply because 4 of the containers equals one gallon
Answer:
x = 4, x = 3/2
Step-by-step explanation:
3(x - 4)(2x - 3) = 0
x - 4 = 0 , or 2x-3 = 0
x = 4, x = 3/2
Using algebra...
n and n+2 are the integers
n*(n+2)=288
n^2+2n=288
n^2+2n-288=0
288=2*2*2*2*2*3*3=(2*2*2*2)*(2*3*3)=16*18 and 18-16=2
factor
(n+18)(n-16)=0
n+18=0
n=-18
n+2=-16
this is one solution
n-16=0
n=16
n+2=18
this is another solution
as you can see, it's just a matter of factoring
288
using arithmetic...
√288=16.97≈17
16 and 18 are the integers (as well as -16 and -18)
