8 is the answer find the complex unit rate and then multiply
The answer is x=1.
Step one is Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
-2x + 2 = -2 • (x - 1)
Step two is
Equations which are never true :
<span> 2.1 </span> Solve : -2 = 0
Step three
Solving a Single Variable Equation :
<span> 2.2 </span> Solve : x-1 = 0<span>
</span>Add 1 to both sides of the equation :<span>
</span> x = 1
One solution was found :
<span> x = 1</span>
Answer:
The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%
Step-by-step explanation:
First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .
