Answer:
$ 1850
Step-by-step explanation:
As it is simple interest, the interest will be same each year.
Interest = 2312.50 - 2081.25 = $ 231.25
The amount borrowed = 2081.25 - 231.25 = $ 1850
2 (x - 9) = -8x - 8 solve for x
x=1
(x - 9) = -8x - 8 solve for x
x= 1/9
x=0.1
Step-by-step explanation:
Rachel will owe Adam 10,722.6 at the end of the 2 years.
A^2 + b^2 =c ^2
7.3^2 + 4.8^2 = c^2
C^2= 76.33
C= square root of 76.33
C= 8.7
Which is d
2⁽ˣ⁺¹⁾ = 3ˣ
ln[2⁽ˣ⁺¹⁾] = ln(3ˣ)
(x+1).ln(2) = x.ln(3)
Expand:
x.ln(2) + ln(2) = x.ln(3)
x.ln(2) - x.ln(3) = - ln(2)
x[ln(2) - ln(3)] = - ln(2)
x = [ - ln(2)] / [ln2) - ln(3)
And x = 1.7095
