Answer:
5+4x=-11
Step-by-step explanation: First it says "The sum of 5 and four times a number" which going to be 5+4x because 4 time a number so it's going to be 4x. Then the last thing you will need to do is to add in the equal sign which the whole equation going to be 5 + 4x = -11.

Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25
Is this what you were looking for?
So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =

= 0.9)

=

cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer

90 and 90 cancels out
x = 30So your final answer will be,
there were 30 questions in the exam paper.
