Answer:
Step-by-step explanation:
The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.
So,

Probability of not blue = 1 - Probability of blue

Answer:
y/(x - 10)
Step-by-step explanation:
The quantity is x minus ten, which means that it is (x - 10)
y divided by the quantity = y/(x - 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
Answer:
B
Step-by-step explanation:
The opposite of x is -x
And the opposite of -6 is 6
So -x+6 is the inverse
The cost of 85 shirts is 400+7.5*85=1037.5
The average per shirt is 1037.5/85=12.206
