Question

What is 4(.8x+2.5)<2(.125-.9) ?

Answer 1

we are given

`4(0.8x+2.5)<2(0.125-0.9)`

we have to solve for x

step-1: Simplify right side

`4(0.8x+2.5)<2(-0.775)`

`4(0.8x+2.5)<-1.55`

step-2: Simplify left side

`4*0.8x+4*2.5<-1.55`

`3.2x+10<-1.55`

step-3: Subtract both sides by 10

`3.2x+10-10<-1.55-10`

`3.2x<-1.55-10`

`3.2x<-11.55`

step-4: divide both sides by 3.2

`x<-3.609375`

so,

Answer is
`x<-3.609375`
