Grace recorded the forecasts that a local meteorologist made for one month, as well as the actual weather. The data she collected is shown in the table below. Grace concludes that the meteorologist is always better at predicting the weather when it does not rain.

thats not a system of equations, that is a solution

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

i'm pretty sure the answer is a. decreases with increase in
