Question

josh scored x marks in this math exam. he scored 8 more marks in english than math, and 3 more marks in geography than in math. if he received a total of 200 marks for the 3 subjects, find how many marks he scored in math.

Answer 1

Math = 63

Explanation:

Math = x

Eng = Math + 8

Geo = Math + 3

Math + Eng + Geo = 200

Substitute Eng and Geo with information above

Math + (Math + 8) + (Math + 3) = 200

3Math + 8 + 3 = 200

3Math + 11 = 200

3Math = 200 - 11

3Math = 189

Math = 189 ÷ 3

Math = 63
