Answer & Step-by-step explanation:
2a - b : 2a + b = 1 : 2
2a - b = 1
- Elimination
2a + b = 2
-b - (b) = -1
-2b = -1
b = 0.5
---------------------------------------------------------------------------------
2a + b = 2 Substitution
2a + 0.5 = 2
2a = 1.5
a = 0.75
--------------------------------------------------------------------------------------
a:b
0.75 : 0.5
or
3/4 : 1/2
Hope this helps!!!

<u>ANSWER: </u>
The equation is y = 1.06x, so option D is correct.
<u>EXPLANATION:</u>
Given:
Amount Catherine is paid for an MP3 player=$159.00
The price paid includes a sales tax= 6%
To find:
Equations that can be used to determine the price of the MP3 player before tax?
Solution:
Now, we know that, total cost = selling price of item + sales tax on item
y = x + 6% of x
y = x + 
y = x + 0.06x
y = 1.06x
Hence, the equation is y = 1.06x, so option D is correct.
