<span>Hello,
For this 12x-3x+11>4x-(17-9x)let's rewrite it as:
12x-3x+11>4x-17+9x
Now combine like terms:
9x+11>13x-17
Subtract 9x and add 17 to get:
28>4x
Divide by 4:
7>x or rewritten as:
x<7
Make sense?</span>
45 miles per hour would equal 66 feet per second.
Well, that would be 4 tables to fit 20 people but would not be enough for 2 more people so I would say 5 tables total.
-Hope this helps.
Answer:

Step-by-step explanation:
The slope of a line is the change in the line. It can be found using the formula;
or
.
Substitute in the given points, and solve for the slope;

Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.
6n - 6 = 12
To solve, add 6 to both sides
6n = 18 Dviide both sides by 6
n = 3
