this proof -2(x+1)=8, then x= -5

We have to prove that,

-2(x+1)=8, then x= -5

L.H.S.

By distributive property,

Adding 2 both sides ( Additive property of equality )

Divide both sides by -2 ( Division property of equality ),

= R. H. S

Hence, proved....

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon
