Step-by-step explanation:
The solution set in given as n >3
Because the set does not contain an equal to ( it is not greater than or equal to ) then the dot would be an open circle ( white dot).
The answer is also greater than 3 so the arrow would be pointing to the right.
The answers would be the 3rd and last one.
18 pieces are made. This is because 6 divided by 1/3 (this operation is needed to find the number of 1/3s that can fit in 6) = 18. If you don't know how to divde fraction, tell me. I hope this helps! :D
Answer:
The amount invested in the account that paid 8% was $18,000
The amount invested in the account that paid 10% was $6,000
The amount invested in the account that paid 12% was $26,000
Step-by-step explanation:
Let
3x -----> the amount invested in the account that paid 8%
x -----> the amount invested in the account that paid 10%
$50,000-4x ----> the amount invested in the account that paid 12%
in this problem we have
![8\%=8/100=0.08\\10\%=10/100=0.10\\12\%=12/100=0.12](https://tex.z-dn.net/?f=8%5C%25%3D8%2F100%3D0.08%5C%5C10%5C%25%3D10%2F100%3D0.10%5C%5C12%5C%25%3D12%2F100%3D0.12)
we know that
![3x(0.08)+x(0.10)+(50,000-4x)(0.12)=5,160](https://tex.z-dn.net/?f=3x%280.08%29%2Bx%280.10%29%2B%2850%2C000-4x%29%280.12%29%3D5%2C160)
Solve for x
![0.24x+0.10x+6,000-0.48x=5,160](https://tex.z-dn.net/?f=0.24x%2B0.10x%2B6%2C000-0.48x%3D5%2C160)
![0.48x-0.24x-0.10x=6,000-5,160](https://tex.z-dn.net/?f=0.48x-0.24x-0.10x%3D6%2C000-5%2C160)
![0.14x=840](https://tex.z-dn.net/?f=0.14x%3D840)
![x=\$6,000](https://tex.z-dn.net/?f=x%3D%5C%246%2C000)
![3x=\$18,000](https://tex.z-dn.net/?f=3x%3D%5C%2418%2C000)
![\$50,000-4x=\$26,000](https://tex.z-dn.net/?f=%5C%2450%2C000-4x%3D%5C%2426%2C000)
therefore
The amount invested in the account that paid 8% was $18,000
The amount invested in the account that paid 10% was $6,000
The amount invested in the account that paid 12% was $26,000
