For this case we have:
G: Let the variable representing the amount of initial money in the account.
If you spend
of G then we have:
![G (1- \frac {1} {3}) = G (\frac {3-1} {3}) = \frac {2} {3} G](https://tex.z-dn.net/?f=G%20%281-%20%5Cfrac%20%7B1%7D%20%7B3%7D%29%20%3D%20G%20%28%5Cfrac%20%7B3-1%7D%20%7B3%7D%29%20%3D%20%5Cfrac%20%7B2%7D%20%7B3%7D%20G)
Then spend $20, then we have:
![\frac {2} {3} G-20](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B3%7D%20G-20)
Finally, the expression that represents the money left in the account is:
![\frac {2} {3} G-20](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B3%7D%20G-20)
Answer:
![\frac {2} {3} G-20](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B3%7D%20G-20)
Answer:
Step-by-step explanation:
Por aspa simple:
x²+x-30=0
X +6
X -5
(x+6)(x-5)=0
x+6=0
x=-6
x-5=0
x=5

1/39
Answer:
One of the number is 4 while the other is 7
Step-by-step explanation:
The sum of two numbers is eleven
Let the numbers be x and y
X+ y = 11
One number is thirty-eight less than six times the other
X= 6y-38
X+ y = 11
6y-38 +y= 11
6y+y= 11+38
7y=49
Y= 49/7
Y= 7
X+ y = 11
X+7= 11
X= 11-7
X= 4
Because vol= length x width x height , and assuming that the height is 11.5 because breadth means width but you already have a width then, vol= 11.5 x 7.4 x 11.5, vol = 978.65
