x is the horizontal axis on a graph. It can also represent multiplication or the word "by", for example a room is called 10' x 10' (10 by 10).

Answer:x is a common variable in math. It could also possibly refer to the x-axis on a graph, and is often used as a symbol for multiplication."f(x) = ... " is the classic way of writing a function. For example f(x) = x+3, then f is the function, x is the input, (x+3) is the output.sine (x), cosine (x), are functions in trigonometry
How about: 2x = 16 meaning that x = 8
It all depends upon which helicopter you mean: 1 knot ≈ 1.15 mph A Wessex helicopter had a max speed of 115 knots, meaning it could cover 93 miles in 93 ÷ (115 x 1.15) x 60 mins ≈ 42.16 mins A Wasp helicopter had a max speed of 120 knots, meaning it could cover 93 miles in 93 ÷ (120 x 1.15) x 60 mins ≈ 40.41 mins A Sea King helicopter had a max speed of 125 knots, meaning it could cover 93 miles in 93 ÷ (125 x 1.15) x 60 mins ≈ 38.79 mins A Lynx helicopter had a max speed of 160 knots, meaning it could cover 93 miles in 93 ÷ (160 x 1.15) x 60 mins ≈ 30.31 mins Those figures are from pre 1980. A Lynx in 1986 reached 249.1 mph, meaning it could cover 93 miles in 93 ÷ 249.1 x 60 mins ≈ 22.40 mins An unofficial record of 299 mph by a Sikorsky X2 (compound helicopter) in 2010 means it could cover 93 miles in 93 ÷ 299 x 60 mins ≈ 18.66 mins
this is actually an equation let the 'sum' be x we are assuming r means are meaning = so x/6 = 7 x=42 so thats the answer
