Answer:
The opposite sides of the rectangle are parallel.
Step-by-step explanation:
If that is true for all parallelograms and a rectangle is a parallelogram, then it should be true for a rectangle too, I think.
I would think you would do divide the number by 2 and add 15 to it,But not sure.
You would use PEMDAS
P stands for parentheses, x-5 can’t be simplified, so on to E.
E stands for exponent so next you would square x-5 getting x^2-10x+25.
M stands for multiplication, you multiply your result from E by -2. So, -2(x^2-10x+25)+8. And then -2x^2+20x-50+8.
D stands for division, and there is none so moving on.
A stands for addition, and so we add next. -2x^2+20x-42.
You can’t simplify any further so there you go!
Hope this helps!
Answer: The answer is 48 cows.
Step-by-step explanation: Given that a farmer bought a number of equally priced cows at $480. After 3 died, the farmer sold the remaining cows for a total of $495 and the price per cow was $1 more when he sold them than when he bought them. We need to find the number of cows he bought originally.
Let, 'x' be the number of cows he bought originally each at a price of '$y'.
Then, we have
Subtracting the first equation from the second, we have
This gives, y = 10 or y = -16. Since price of a cow cannot be negative, so y = 10.
Thus,
Thus, the total number of cows originally bought is 48.
