Answer:
Step-by-step explanation:
Let x represent the number of spelling questions in the test.
Let y represent the number of vocabulary questions in the test.
Mrs morals wrote a test with 15 questions covering spelling and vocabulary. This means that
x + y = 15
Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100. This means that
5x + 10y = 100 - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
5(15 - y) + 10y = 100
75 - 5y + 10y = 100
- 5y + 10y = 100 - 75
5y = 25
y = 25/5 = 5
x = 15 - y = 15 - 5 = 10
