8 (x - 3) + 8 = 5x - 22

First, expand. / Your problem should look like: 8x - 24 + 8 = 5x - 22
Second, simplify 8x - 24 + 8 to 8x - 16. / Your problem should look like: 8x - 16 = 5x - 22
Third, subtract 5x from both sides. / Your problem should look like: 8x - 16 - 5x = -22
Fourth, simplify 8x - 16 - 5x to 3x - 16. / Your problem should look like: 3x - 16 = -22
Fifth, add 16 to both sides. / Your problem should look like: 3x = -22 + 16
Sixth, simplify -22 + 16 to -6. / Your problem should look like: 3x = -6
Seventh, divide both sides by 3. / Your problem should look like: x = - \frac{6}{3}
Eighth, simplify \frac{6}{3} to 2. / Your problem should look like: x = -2

Answer: x = -2

Assignment
KengaRu [80]

Answer:

Total Price = 1.07(0.65x)= 0.6955x.

Step-by-step explanation:

The discount percentage is, <em>d</em>% = 35%.

The sales tax percentage is, <em>s</em>% = 7%.

The variable <em>x</em> represent the original cost of the item(s).

The discount is subtracted from the original amount.

So, the discounted amount will be, 0.65x.

And the sales tax is added to the original amount.

So, the value of tax plus price will be, 1.07x.

Then the final price of the item(s) will be:

Total Price = 1.07(0.65x)= 0.6955x.

Write an equation in point – slope form from the line through the given point with the given slope. (-10, -1); m=-1
Alexxandr [17]

Answer:

y = -x - 11

Step-by-step explanation:

We know the equation must be: y = -x + c

However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.

So:

-1 = -(-10) + c

-1 = 10 + c

so c = -11

So our equation is:

y = -x - 11
