The value of the x-intercept for the graph of 4x-5y=40 is

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
