Let's work on the triangle first. The x intercept of 2y=27-3x is
0 = 27 - 3x
3x = 27
x = 9
So A(9,0)
B is the meet of 2y=27-3x and y=3x
2y=27-y
3y=27
y=9
y is the height of OAB; we don't really need x
Area(OAB) =
Now we have to subtract
Area = 40.5 - 24.3 = 16.2
Answer: 16.2
Answer: The answer is C: 60

Answer:
Jenny save 4 times for the month
Step-by-step explanation:
Given Jenny has saved over the last 12 months.
She saved either or a month.
Let the number of months to save be x
Let the number of months to save be y
Total period is 12 month.
Jenny has saved $3,800 over the last 12 months.
Dividing both side from 50 we get,
Now Multiplying equation 1 by 5 we get,
Now Subtracting Equation 3 by equation 2 we get,
Substituting the value of y in equation 1 we get,
∴ Jenny save 4 Months of and 8 Months of in a 12 month duration
Answer:
4 times
Step-by-step explanation:
Let,
250 = x
350 = y
x + y = 12
250x + 350y = 3,800
Solve the system.
x = 4 and y = 8
Therefore, Jenny saved $250 for 4 months and $350 for 8 months.
