Step-by-step explanation:
-5x < 25
Divide both sides by the coefficient of -5
-5x/-5 < 25/-5
x > -5

They vary directly (im just writing this cause my answer wasn’t long enough)
Subtract 8 from each side:
-4x = 40
Divide each side by -4 :
x = -10
Scale = 1cm:3km
Therefore area of lake = 81Km
1:3 = x:81
= 27:81
Therefore the area on map is 27cm
