Answer:
B. infinitely many solutions
Step-by-step explanation:
–2(–x + 9) = 2(x – 9)
Distribute the -2 on the left side. Distribute the 2 on the right side.
2x - 18 = 2x - 18
Add 18 to both sides.
2x = 2x
The equation means two times a number x is equal to two times the same number x. This is true for all numbers x. Every number is a solution of this equation.

Hello,
Correct Answer is <u>12/3</u>
<h3>Step-by-step explanation:-</h3>
For angle theta, perpendicular side is AB=12 and hypotenuse side is BC=13.
The sine of angle is equal to the ratio of perpendicular side to the hypotenuse side. So, sine of angle theta is:-
So, sine ratio angle is 12/3.
{ Note: Here, the ratio is written using slash (/) symbol as it is asked to use the slash symbol in the answer. }

14 < n - 3
We must isolate n. To do that we must bring -3 to the left side of the equation. To make -3 zero on the right side of the equation and bring it to the left side you must add 3 to both sides like so...
14 + 3 < n + (-3 + 3)
17 < n + 0
17 < n
Hope this helped!

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.
