Answer:
29t + 24
Step-by-step explanation:
5(5t + 6) + 2(2t - 3)
Open Parentheses first.
5* 5t = 25t
5 * 6 = 30
25t + 30 + 2(2t - 3)
Open others
2 * 2t = 4t
2 * 3 = 6
25t + 30 + 4t - 6
Match like terms
29t + 24
First, determine the effective interests given both interest rates.
(1) ieff = (1 + 0.068/12)^12 - 1 = 0.07016
(2) ieff = (1 + 0.078/12)^12 - 1 = 0.08085
Calculating the interests will entail us to use the equation,
I = P ((1 + i)^n - 1)
Substituting the known values,
(1) I = ($5125)((1 + 0.07016)^1/2 - 1)
I = $176.737
(2) I = ($5125)(1 + 0.08085)^1/2 - 1)
I = $203.15
a. Hence, the greater interest will be that of the second loan.
b. The difference between the interests,
d = $203.15 - $176.737
$26.413
Solve the above equations,
First term is -13.
Greater than 1 because left side is a fraction less than 1 and right side is a number greater than 1.
The left side being a fraction less than 1 could only mean that you have to multiply a number greater than 1 to the other side. And since the other side is a number greater already than 1 then multiplying the left side to the right side must result in a number greater than 1.
X + 13 = -4
x = -4 - 13
x = - 17
I am thinking it is the first one..solution is -17
