Answer:
it's a rectangle so the area is 6×8=48
Let X be the amount of water one person can use.
Multiply that by 5 people to get 5X
That amount plus what they already used ( 4885.78) needs to be less than or equal to the amount they are limited to ( 7250.50 ).
Now write out the equation to get : 5x + 4885.78 ≤ 7250.50
178-35=143
143/5= 28.6
he paid $28.6 every month
Answer:
\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]
Step-by-step explanation:
Given is a matrix 3x3 as
![\left[\begin{array}{ccc}1&0&2\\-3&1&4\\2&-3&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%262%5C%5C-3%261%264%5C%5C2%26-3%264%5Cend%7Barray%7D%5Cright%5D)
|A| =2 hence inverse exists.
Cofactors are 16 20 7
6 8 3
2 2 1
Hence inverse =
![\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D16%266%262%5C%5C20%268%262%5C%5C7%263%261%5Cend%7Barray%7D%5Cright%5D)
Answer: Car B will catch up with A when the distance travel by the two are equal
Recall Speed = Distance/Time
Distance =Time * Speed
Car A; D=60T1
Car B; D=70T2
Where T1= T2+1
60T1=70T2
60(T2+1)= 70T2
60T2+60=70T2
10T2=60
T2=6hrs
4pm +6hrs
10pm car B catches up with A
