Lol i need help again on math

x < 7

Step-by-step explanation:

84 - 6x > 42         First subtract 84 from both sides

-84          -84

   -6x > -42    

 x < 7      Remember when dividing both sides of an inequality by a negative number, the sign flips and becomes its opposite.

In this case > will become <.

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
