Maurinko [17]

Answer:

<h2>b=2</h2>

Option A is the correct option.

Solution,

4 - 2(b - 6) = 12 \\ or \: 4 - 2b + 12 = 12 \\ or \: 4 + 12 - 2b = 12 \\ or \: 16 - 2b = 12 \\ or \:  - 2b = 12 - 16 \\ or \:  - 2b = -  4 \\ or \: b =  \frac{ - 4}{ - 2}  \\ b = 2

Hope this helps...

Good luck on your assignment..

The ratio of isabellas money to shanes money is 3:11. If isabella has $33, how much money do Shane and Isabella have together?
solong [7]
The ratio of Isabella’s money to Shane’s money is 3:11

Isabella has $33.   

We can make a proportion to solve for how much money Shane has.   
A proportion is two ratios that are set equal to each other.  

Let’s call Shane’s money ‘S’   

We get this proportion:   3/11 = 33/x   

If we cross multiply we get:   
(33) * (11) = (3) * (x)   

Simplifying it, we get:
363 = (3) * (x)   

Divide both sides by 3, we get:
x = 121   

However, the question asks how much money they have together. 

Isabella + Shane = Total
33 + 121 = $154   

<span>They have $154 together.</span>
