Final answer:

To solve the equation, subtract 11 over 20 from both sides and simplify.t is equivalent to option b: 6 over 20 before simplification

Step-by-step explanation:

To solve the equation 17 over 20 equals j plus 11 over 20, we need to isolate j. We can do this by subtracting 11 over 20 from both sides of the equation. This gives us
17 over 20 minus 11 over 20 equals j plus 11 over 20 minus 11 over 20.
Simplifying, we get:
6 over 20 equals j.
So the value for j is 6 over 20, which is the same as 3 over 10 or 0.3.To determine the value for j in the equation 17/20 = j + 11/20, we need to isolate j on one side of the equation. This can be done by subtracting 11/20 from both sides:17/20 - 11/20 = j

Since the denominators are the same, we subtract the numerators:(17 - 11)/20 = j

6/20 = j

Therefore, the value for j is 6/20, which simplifies to 3/10. However, this value does not match any of the provided options exactly, yet it is equivalent to option b: 6 over 20 before simplification
