Answer:
8%
Step-by-step explanation:
The amount repaid is ...
A = P(1 +rt)
Filling in the given values, we can find r.
(18·28) = 450(1 +r(18/12)) . . . . . t is in years
504 = 450 + 675t
54/675 = 0.08 = 8%
The simple interest rate on the loan is 8%.
Explanation:
Step 1) Add
4
to each side of the equation to isolate the
x
term while keeping the equation balanced:

Your distance(d) is 1,814.4
1814.4 m = 5.6t square
then you square root 5.6t
![\sqrt{1814.4} = \sqrt{ {5.6t}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B1814.4%7D%20%3D%20%5Csqrt%7B%20%7B5.6t%7D%5E%7B2%7D%20%7D%20)
the square root eliminates the square
![\sqrt{1814.4} = 5.6t](https://tex.z-dn.net/?f=%20%5Csqrt%7B1814.4%7D%20%3D%205.6t)
you square root 1,814.4 m
![42.6 = 5.6t](https://tex.z-dn.net/?f=42.6%20%3D%205.6t)
(I rounded 42.6) then divide 42.6 by 5.6
![7.6 = t](https://tex.z-dn.net/?f=%207.6%20%3D%20t)
(I rounded 7.6)
