Let's say that the value invested in the account with a rate of 8% is "x", then the amount invested in the account with a rate of 12% is:
To calculate the total interest we need to calculate the interest of each individual account and sum them:
The total interest is the sum of the two expressions above:
The value invested in the account with 8% interest is 830, the one invested in the account with 12% interest is 1280.
It already is a fraction though. I assume you mean to simplify it. You can simplify fraction by taking out the greatest common factor(that they share) in the denominator and numerator. In this case the denominator and numerator share the factor 5. So you if you divide the numerator and denominator by 5 you get 3/10 or the simplest form of the fraction.
The answer is
The answer is
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, If the given equation is and
.
Step-by-step explanation:
The given is,
...............................(1)
...............................(2)
Step:1
Solution can be obtained by Elimination method,
Equation (1) is multiplied by (-1) ( Eqn (1) × -1 )
..............................(3)
Substrate the equation (1) and equation (3),
( - )
we can cancel the minus because it is available in both sides,
x = 4
From the value of x, Equation (2) becomes,
(Value of y in terms of x)
Where, x = 4
Step:2
Check for solution,
.....................................(2)
Substitute the values of x and y,
4 + 4 = 8
8 = 8
Result:
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, where x=4. If the given equation is and
