(320,000/4000)*12= 960 USD. 320,000 divided by 4000 is 80, there are 12 months in a year. 12 times 80 is 960. So 960 Dollars is your answer.
Since you have two unknowns, you must formulate 2 equations in order to solve the system. Let x be the numbers of dimes and y be the number of quarters. The equations are:
x + y = 61
y = x + 3
Since a dime is 1/10 of a dollar and a quarter is 1/4 of a dollar,
(1/10)x + (1/4)y = 10.90
We made 3 equations. The system is overspecified. Let's just use the first two equations and apply it to the third for verification.
x + (x + 3) = 61
Solving for x,
x = 29
y = 29 + 3 = 32
Verifying,
(1/10)(29) + (1/4)(32) = 10.90
Hence, there are 29 dimes and 32 quarters.
Excluded values are the values that make the denominator equal to 0 because x/0 is undefined.
1)
9x - 45 = 0
9x = 45
x = 5
The excluded value is x = 5.
2)
2x + 48 = 0
2x = -48
x = -24
The excluded value is x = -24.
Answer: The midpoint (1,5.5)
Step-by-step explanation:
( 5,5) ( -3,6)
5+-3= 2/2 = 1
5 + 6 = 11 /2 = 5.5
Perimeter= 4x+8 and Area= 2x+1x^2+2
I posted a photo on how I found these two answer.
Hope this helped
