This is a basic algebraic equation

And will be using PEMDAS to solve

P: Parentheses
E: exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction

If you are unaware of PEMDAS this is the order at which you solve algebraic equation. So start from “P” and end with “S”


X= 2/3

2/3^3 Times 3 Divided by 2/9 + 9(2/3) - 7 - 6(2/3)

Now, personal I’d choose to convert fractions to decimals to simplify solving the equation. I doubt this is the only way to solve for the equation but I find this is the easiest

To convert a fraction to decimal you divide the numerator by the denominator.

So 2/3 is 0.666667
And
That means 2/9 is 0.222222

0.666667^3*3/0.222222+9(0.666667)-7-6(0.666667)

Making you answer roughly -0.999989

Hope this helps, but I’m not sure if this is completely right or not

Murrr4er [49]
First you need to know how many pounds of carbon dioxide you get when burning 1 gallon of gasoline. That number is 19.64 pounds

To get the number of pounds released when entire tank is burned you need to multiply gas tank volume and number of pounds you get when 1 gallon is burned.

17.2 * 19.64 = 337.808

15. The dollar amount y that remains to be repaid on a loan x months after the loan is issued is represented by y=-1000x + 8000.
irina [24]

Answer:

1) $8000

2) $1000

3) 8 months, since y represents our remaining amount to be paid, we set it equal to 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.

Step-by-step explanation:

We have the equation y = -1000x + 8000 which follows the linear equation:

y = mx + b, where m is our slope and b is our y-intercept

1) The initial balance can be found with our constant "b" which in this case is 8000. You can also plot the function of y and you will find that 8000 is the intercept when x = 0, aka the start

2) We can calculate the rate of change for when the loan is repaid by looking at the slope "m", in this case it is 1000. It subtracts 1000 each month, meaning $1000 is being payed and taken out of the bank account

3) To find how many months it will take for the loan to be repaid, let's solve for x when y = 0.

0  = -1000x + 8000

-8000 = -1000x

8 = x

It will take 8 months. Why? Since y represents our remaining amount to be paid, we set it = 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.
