How do i know when to flip my sign in an inequality ex- 37x> 8=48

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

a) 7x=7

step-by-step explanation:

you can use a^2+ b^2=c^2
