Answer:
Step-by-step explanation:
First, you should distribute the -1 on the right.
Next, add 8n to both sides. This should cancel out the 8n.
Now, add 8 to both sides. This will get n by itself.
Your answer is n = -2.
Answer:
Sound can travel 12 miles per minute.
Step-by-step explanation:
Speed equation is distance divided by time.
So we have 1 mile per 1/12 of a minute.
Let’s write the equation.
Speed of sound = 1 / 1/12
Multiply by the reciprocal.
1 * 12 = 12.
Answer:
Therefore,
Step-by-step explanation:
Given:
To Solve:
x = ?
Solution:
Addition and Subtraction is explain by some examples say,
5 + 3 = 8
5 - 3 = 2
But in case,
5 + - 3 is also written as
5 -3 = 2
if it is
5 - - 3 then it becomes
5 +3 = 8
That means
"+" and "-" will become "-"
"-" and "-" will become "+"
"-" and "+" will become "-"
"+" and "+" will become "+"
Therefore,
will become
Take common 'x' out then
Therefore,
