Cost= (5.50d+6.00p) +6.50
Coefficients: 5.50 and 6.00
Constant: 6.50
Variables: d and p
So to solve this problem, we can either do guess and check, or solve an equation.
Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.
So, to begin, let's define our unknown.
We can represent the number as "n"
So, 6 percent of "n" is equal to 270
To find a "percent" of a number, you need to multiply the number by the percentage.
So, 6 percent as a decimal is .06
This is because a percent is a fraction divided by 100 (6/100)

The number is 4,500
1.2 x 10^-6
You have to move the decimal so that your number is between 1 & 10. Then you write that number times 10 then add the exponent. Check on what makes it positive or negative <span />
Answer:
x=-7
Step-by-step explanation:
5x-2x+1=3x-6-x first combine like terms
3x+1=2x-6 combine like terms by subtracting 2x from both sides
x+1=-6 subtract 1 from both sides
x=-7
