I think it’s 1/2. i’m not sure though sorry
        
                    
             
        
        
        
Answer:
a = d/2b - 2/b
Step-by-step explanation:
2ab+4=d
2ab=d-4
a= d/2b - 4/2b
<h2>a = d/2b - 2/b</h2>
 
        
             
        
        
        
Answer: y = 5d + 7 / c - 3
Step-by-step explanation:
Step 1: Add -3y to both sides
cy - 7 + -3y = 5d + 3y + -3y
= cy - 3y - 7 = 5d
Step 2: Now, add 7 on both sides
cy - 3y - 7 +7 = 5d +7
= cy - 3y = 5d +7
Step 3: Factor out y
y(c - 3) = 5d + 7
Step 4: Divide both sides by c-3
y(c - 3) / c - 3 = 5d+7 / c-3
Your answer for this should be
y = 5d + 7 / c - 3
Hope this helped!
 
        
             
        
        
        
Answer:
Step-by-step explanation:
                               To isolate <em>a</em>, we add -3.75 to both sides.
                                                <em>a</em>-(-3.75)=6.11
                                    <em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>
                                                             <em>a</em>=6.11<em><u>+(-3.75)</u></em>   Simplifying, we get:   
<em>a</em>=2.36
