Step-by-step explanation:
350-75%=87.5\\so 350-87.5\\=262.5\\$262.5 dolla profit\\
If we have a number represented by n, we have 20 is equal to, so 20=something. That something is "5 less than twice a number". 5 less than something means something-5, and something-5=20. Since 5 is less than twice a number, and twice a number is n+n=2n, we have 2n-5=20
Actually solving the problem, we can start by adding 5 to both sides, resulting in 2n=25. Next, we can divide both sides by 2 to get n=12.5
Step-by-step explanation:
The vertex of the angle goes in the middle. If we trying to reference to the value of angle a for example, You can say
Multiply first equation by 2
2x - 6y = 14
-2x + 6y = 6
-------------------add
0x + 0y = 20
0 ≠ 20
answer
zero solution
