. A person weighing 120 pounds has about 20 pints of blood in their body. Which equation below represents the relationship between pints of blood, b, to a person's weight, w?

Step-by-step explanation:

Given

Required

Determine the equation that binds both parameters

First, we need to determine the constant of proportionality using:

Where k represents the constant.

Substitute 120 for w and 20 for b

Divide both sides by 20

Using the same formula, substitute 6 for k

Hence:

The equation is represented as

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
