Question

Mrs. Morales wrote a test with 14 questions covering spelling and vocabulary. 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.

Answer 1

There are 10 spelling questions and 5 vocab questions

Explanation:

5 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:x+y=15

5x + 10y= 100

So: x+y=15

x = 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10
