- We have a bag with 4 white chips and 6 black chips
- Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?
4 white and 6 black
4 + 6 = 10
Choosing the first white chip : 
Since we took one out , now
3 white chips , 6 black chips
3 + 6 = 9
Choosing another white chip :

Answer:
x = -5, 2
Step-by-step explanation:
The first step to factor the equation is removing any factors/like terms that all of the variables share.
In the equation
, all numbers are multiples of 2, therefore you can factor out 2 from to equation

Next, you can factor the equation in the parenthesis. Since x^2 is not multiplied by anything, you know that the factors of x^2 must be x and x. Therefore, the two factors of -10 must add up to 3. The only two factors of -10/x that add up to 3 are 5 * -2.
The factors of the equation are then (2)(x+5)(x-2)
Lastly, set up only the factors containing a x to 0 in order to solve for x-intercept.
x+5 = 0; x= 0-5 ; x = -5
x - 2 = 0; x = 0 + 2; x = 2
Answer:
6 3/4
Step-by-step explanation:
to write 54/8 into the mixed number and in the simplest form
we first simpify 54/8 which is 27/4
to convert 27/4 into a mixed number we first see how many times does 4 goes into 27 with the remainder. 4 goes into 27 6 times with the remainder of 3. 4 goes into 27 6 times so, 6 will be the whole part 3 remainder will be the numerator and 4 will be the denominator. like 6
