If 2a-b:2a+b=1:2, find the value of a:b.

a:b = 3:2

Step-by-step explanation:

You are given:

 2a - b        1

=

2a + b        2

Then, through cross-multiplication, we get:

4a - 2b = 2a + b, or

2a = 3b

We want the value of the ratio a:b.  To obtain this, divide both sides by b, which results in

  2a

= 3

    b

Finally, we divide both sides by 2, obtaining the desired ratio:

a:b = 3:2

34

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
