Answer:
x = 36
Step-by-step explanation:
We have the equation (2/9)x + -2 = 6.
First, notice that adding a negative number is the same as subtracting by that number. So:
(2/9)x + -2 = 6
(2/9)x - 2 = 6
Now, we need to isolate the variable. Add 2 to both sides to cancel out the -2 on the left:
(2/9)x -2 + 2 = 6 + 2
(2/9)x = 8
Now multiply both sides by 9/2 to cancel out the 2/9 on the left:
(9/2) * (2/9)x = 8 * (9/2)
x = 72/2 = 36
Thus, x = 36.

On the 40th and the 80th you will receive both a free beverage and a free appetizer. You can find this by simply finding the multiples of both number up to 100 (or a little more than 100) to find out on which dates you'd get bothe an appetizer and beverage for free. Here are the multiples of both, to prove this answer.
- 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104.
- 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
Thus making 40 and 80 the answers. I hope this helps!
Answer:
.16hertz
Step-by-step explanation:
When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)
