2x - 3(x + 4) = -5
2x - 3x - 12 = -5
-x - 12 = -5
-x = -5 + 12
-x = 7
x = -7
The answer is: x = -7.
The answer is 28.09 g. I hope this helped.
Answer:
Set up an equation
-4+x=4 Add 4 to each side
x=8
So
-4 plus eight is 4
Answer:
The sequence converges to 1
Step-by-step explanation:
Given

Description of the sequence
The given sequence follows:
i.e.
For every term,
In other words,
as the value of n increases, 
approaches 1
<em>Hence, (c) is true</em>
The first solution contributes 0.78*1 = 0.78 L of acid.
The second contributes 0.64*6 = 3.84 L of acid.
There will be 7 L total of the new solution, and 3.84 + 0.78 = 4.62 total L of acid in it. So the new solution has a concentration of 4.62/7 = 0.66, or about 66%.
