What is 3x-15+6x+2=45

x = 6.44 (rounded)

Step-by-step explanation:

First, combine like terms:

3x + 6x + 2 - 15 = 45

(3x + 6x) + (2 - 15) = 45

(9x) + (-13) = 45

9x - 13 = 45

Isolate the variable, x. 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 is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 13 to both sides:

9x - 13 (+13) = 45 (+13)

9x = 45 + 13

9x = 58

Next, divide 9 from both sides:

(9x)/9 = (58)/9

x = 58/9

x = 6.44

the two may have that, even a breakdown is probably offered

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
