She missed 6 questions.
Step-by-step explanation:
88% can be written as (88/100) or as 0.88.
You can set this as a ratio problem which is,
88/100 = correct/50
correct = (88/100)*50 <em>(multiply both sides by 50)</em>
correct = 44
So, 50 (total questions) - 44 = 6 incorrect questions

Answer:
Ans => 22
Step-by-step explanation:
A mathematical theorem states that vertically opposite angles are equal.
Hence, we have:
3x - 14 = 4(x-9)
3x - 14 = 4x - 36
solving for x by collecting like terms, we have:
-x = -22
=> x = 22
