Answer:
c = 3
Step-by-step explanation:
You are solving for the variable, c. Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, subtract 1 from both sides of the equation:
3c + 1 = 10
3c + 1 (-1) = 10 (-1)
3c = 10 - 1
3c = 9
Next, divide 3 from both sides of the equation:
(3c)/3 = (9)/3
c = 9/3
c = 3
c = 3 is your answer.

Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.
Distance = speed × time
3x + 15 = 4x . Subtract 3x from both sides
15 = 4x-3x
15 = x The time is 15 seconds.
At that point their distances will be equal at 60 feet.
3(15) + 15 = 60
4(15) = 60

Answer: The distance in kilometers is equal to the distance in miles multiplied by 1.609344. Since one mile is equal to 1.609344 kilometers, that's the conversion ratio used in the formula. So 5 kilometers is approximately 3.1 miles
Answer: 3.10685
Step-by-step explanation:
Since 1 kilometer is equal to 0.62137 miles, and we have 5 kilometers, we simply multiply 5 by 0.62137 to convert 5 kilometers to miles.

Complete the net worth statement by determining the total assets and total liabilities. What is the net worth?
A) $200
B) $2,000
C) $10,700
D) $12,700
Answer:
B
Step-by-step explanation:
1. Add all of the assets($12,700) and all of the liabilities($10,700).
2. Subtract the liabilities from the assets.
The total net worth of the given assets and liabilities is $2000.
What is the net worth?The net worth is the difference between the total assets and the total liabilities.
net worth = assets - total liabilities
The total of all the assets is $12,700 and the total of all of the liabilities is $10,700.
net worth = assets - total liabilities
net worth = $12,700 - $10,700
= $2000
Therefore, the total net worth of the given assets and liabilities is $2000.
