x = 4/5 = 0.8

y = (4/x * x) + √x + 0.2 - 5x.

First, let's plug 0.8 in for x

y = (4/0.8 * 0.8) + √0.8 + 0.2 - 5(0.8)

(4/0.8 * 0.8) the 0.8s cancel out leaving just 4

y = 4 + √0.8 + 0.2 - 5(0.8)

5 * 0.8 = 4

y = 4 + √0.8 + 0.2 - 4

Add all the terms together

y = 1.09.

IceJOKER [234]

Answer:

7.7 pounds = 3.5 kilograms

Step-by-step explanation:

Given that,

Weight of a gallon of liquid = 7.7 pounds

We need to find weight in kilograms.

We must know the relation between pounds and kilograms and it is as follows :

1 kilogram = 2.20 pounds

or

1 pounds = (1/2.2) kilograms

7.7 pounds = (7.7/2.2) kilograms

= 3.5 kilograms

Hence, 7.7 pounds is equal to 3.5 kilograms.
