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:
C
Step-by-step explanation:
The area of a circle is pi * r^2.  The radius is 7 because the diameter is 14 so the radius is 14/2.  The square of 7 is 49.  Pi is approximately 3.14, so 49 * 3.14 is about 154.
