Answer: (i) 4x - 40 = 76

(ii) 29 questions

Step-by-step explanation:

Let the total number of questions be x.

Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become

4x - 40 = 76

To find the value of x , add 40 to both sides

4x = 116

divide through by 4

x = 29

Therefore , there are 29  questions on his math test
