Answer:

6% of the changes were from incorrect to​ incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65​% of the changes were from incorrect answers to correct

29​% were from correct to incorrect

P% were from incorrect to incorrect

So

65 + 29 + P = 100

P = 100 - 94

P = 6

6% of the changes were from incorrect to​ incorrect

R – 26 = 68. what is the value of r
dedylja [7]

Answer:

r = 94

Step-by-step explanation:

Solve the equation by isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 26 to both sides:

r - 26 (+26) = 68 (+26)

r = 68 + 26

Add:

r = 94

r = 94 is your answer.
