An airport runaway measuring 450m is drawn to a scale of 1cm to represent 100m.Find its length in the drawing.​

To solve for the y value, you must start by plugging in your given x value for x in your equation. this leaves you with: 5(0.3) + 2y = 20next, multiply across the parenthesis to simplify your equation. 5 x 0.3 = 1.5so, rewrite your equation to match that calculation: 1.5 + 2y = 20next, begin to isolate your variable by subtracting 1.5 from both sides of the equation to keep it balanced. this realists in: 2y = 18.5finally, isolate y to solve. to do this, divide both sides of the equal sign by 2 to maintain balance in the equation. this leaves you with the final y-value being 9.25. i hope this ! : )
