Answer:
11/35
Step-by-step explanation:
There are a total of 21 people in the group, 12 of whom are not Democrats. The members are selected in succession. The probability the first member isn't a Democrat is 12/21.
Now there are 20 people remaining, 11 of who are not Democrats. So the probability the second member isn't a Democrat is 11/20.
The total probability is (12/21) (11/20) = 11/35
The student wants to prove they are the same by adding the two systems together, and keeping the second equation the same.
So add these two:
6x - 2y = 3
<u>5x + 3y = 4</u>
11x + y = 7
So the answer will be the last choice:
<span>Show that the solution to the system of equations 11x + y = 7 and 5x + 3y = 4 is the same as the solution to the given system of equations</span>
Answer: 32
Step-by-step explanation:
1.) Write the initial equation: 2(9+7)
2.) Add the values in the parentheses: 2(16)
3.) Multiply the value in the parentheses by 2: 2(16) = 32
