George brought a box of fruit that weighed 3 1/2 kilograms. if he gave away 2 5/7 kilograms of fruit to his friends, how many kilograms does he have left?

i got 142 as my answer

step-by-step explanation:

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
