Answer: A, 8125
Step-by-step explanation:
3,725 + 2800 + 700 + 900
3725 + 2800 = 6525
700 + 900 = 1600
6525 + 1600 = 8125
Answer:
n = -8
Step-by-step explanation:
The variable has 4 subtracted and that quantity is multiplied by 5. You can find the value of the variable by reversing these operations, in reverse order. That means you first divide both sides of the equation by 5:
5(n-4)/5 = -60/5
n -4 = -12 . . . . . . simplify
Then you undo the subtraction of 4. You accomplish that by adding 4 to both sides of the equation.
n -4 +4 = -12 +4
n = -8 . . . . . . . . . simplify
_____
This equation can also be solved by first eliminating parentheses. Then you have
5n -20 = -60
Now, the variable is multiplied by 5, then 20 is subtracted from the sum. Reversing these operations in reverse order, we first add 20 to both sides of the equation:
5n -20 +20 = -60 +20
5n = -40 . . . . . . . . . . . . . simplify
Then we undo the multiplication by dividing both sides of the equation by 5:
n = -8
_____
The rule to remember is "whatever you do to one side of the equation must also be done to the other side". This is what keeps the equal sign valid.

Answer:
1/6
Step-by-step explanation:
People who answered less than 1/2 were: 2 + 1 + 3 = 6 people.
There are a total of 36 people.
People who answered their calls before the second ring were only 6/36.
When we simplify the fraction, we get 1/6.
So, the answer is 1/6
