X(x+2)=-1
X=-1
X=-3
I’m not really sure of my answe but I tried my best so good luck!!
The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.

Answer:
D There is an infinite number of solutions to the system of equations
Step-by-step explanation:
When you put the first equation in standard form by dividing it by 2, you get ...
x -2y = 4
When you put the second equation in standard form by dividing it by 8, you get ...
x -2y = 4
These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.
There is an infinite number of solutions.
The answer for this question is a) 2$
He bought 1500 shares (12000/8)
and sold all of them for 15000 which means that he sold each share for 10$ (15000/1500)
So he got got a profit of 2$ (10$-8$)
Answer:
Ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
Step-by-step explanation:
Let the number of red fish and blue fish in the large tank are x and y respectively.
Similarly ratio of red fish and blue fish in the small tank are x' and y' respectively.
Since in each tank ratio of the red fish to blue fish is 333 : 444
That means x : y = 333 : 444
Or
⇒
⇒ y = --------(1)
Similarly x' : y' = 333 : 444
⇒
⇒
⇒ x' = ------(2)
Ratio of the fish in large tank to the fish in small tank is 464646 : 555
So (x + y) : (x' + y') = 464646 : 555
Now we replace the values of x and y' from equation (1) and equation (2)
Therefore, ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
