Hi Quanzia25,
Solution:
45mph
45mph x 4hrs. = 180 miles in 4 hours
45 / 3 = 15
180 + 15 = 195
Answer:
The car has traveled 195 miles.
According to the information given in the exercise, the following expression represents the area of the rectangular garden:
![6\mleft(6.5x+2.5\mright)](https://tex.z-dn.net/?f=6%5Cmleft%286.5x%2B2.5%5Cmright%29)
And the following expression represents the combined area of the walkway around the rectangular garden and the area of the garden:
![6.5\mleft(8x+6\mright)](https://tex.z-dn.net/?f=6.5%5Cmleft%288x%2B6%5Cmright%29)
You can identify that the word "combined" indicates that that expression was obtained by adding both areas.
Knowing the above, you can set up the following equation:
![6(6.5x+2.5)+A=6.5(8x+6)](https://tex.z-dn.net/?f=6%286.5x%2B2.5%29%2BA%3D6.5%288x%2B6%29)
Where "A" is the area of the walkway around the rectangular garden.
Solving for "A", you get the following expression:
![\begin{gathered} A=6.5(8x+6)-6(6.5x+2.5) \\ A=52x+39-39x-15 \\ A=13x+24 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D6.5%288x%2B6%29-6%286.5x%2B2.5%29%20%5C%5C%20A%3D52x%2B39-39x-15%20%5C%5C%20A%3D13x%2B24%20%5Cend%7Bgathered%7D)
The answer is:
Answer:
$10000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 2000 / ( 0.05 × 4 ) = 10000
P = $ 10,000.00
The principal required to
accumulate interest of $ 2,000.00
on a rate of 5% per year for 4 years is $ 10,000.00.
