Here are the answers for 10 and 12
Answer:
The correct answer is C. 1/10.
Step-by-step explanation:
Given that a spinner has 10 equal sections numbered 1 through 10, to determine what is the probability of landing on the 6, the following calculation must be performed:
6 = 1 side only
10 = 10 options
1/10 = X
Therefore, the probability of the spinner landing on the 6 is 1/10.
I assume you mean x squared in the first equation
Because both are equal to y, they are equal to each other so x + 5 = x^2 +3
If we then move everything over to one side, we get x^2 - x - 2 = 0
Then factorise it to (x-2)(x+1) = 0
And solve both parts separately
x + 1 = 0
x = -1
x-2 = 0
x = 2
Sub both values into the simplest equation in this case y=x+5
to get y = 4 and y = 7
