So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.

Answer:
odd
Step-by-step explanation:
If 'a' and 'b' have different parity, the result has odd parity.
__
<u>Assume a=odd, b=even</u>
(5·odd -3·even) = odd
(odd^2 +5·even) = odd
(odd)(odd) +2 = odd
__
<u>Assume a=even, b=odd</u>
(5·even -3·odd) = odd
(even^2 +5(odd)) - odd
(odd)(odd) +2 = odd
_____
The attached verifies this with numbers.
Answer: The average is about $800
Step-by-step explanation:
Most dealers pay their salespeople a 25% commission rate, which is based on gross profit minus a “pack” fee. Pack is usually a few hundred dollars ($800) but can also be a percentage. Example: You sell a used car for $3000 over cost
