no solution, since the graph two parallel lines with no intersect
Answer:

Step-by-step explanation:
When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )
So we have 
==> remove parenthesis and apply signs

==> simplify numerator by combining like terms

and we are done!
Note:
like terms are terms with the same variable and exponent
An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7
The like terms being combined here were (6x² and 4x²) and (5 and -2)
2.54 cm = 1 inch
3.2 inches * 2.54 cm / inch =8.128 centimeters
The answer is: " x = 11 ¼ " ; or write as: " x = 11.25 " .

(40*9) ÷ (4*8) = x ; Solve for "x" ;
(40 * 9 = 360) .
(4 * 8 = 32) .
(360) ÷ (32) = 45/4 = 11 ¼ ; or write as: 11.25 .

Answer:
2
Step-by-step explanation:
Slope (m) is equal to the change in the y-coordinate divided by the change in the x-coordinate.
The change in y= 6
The change in x= 3
6/3 =2
