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

Answer:
y=5/3x-3.4
Step-by-step explanation:
slope is 5/3
We are required to convert the speed from miles per hour to miles per minute;
speed of the car=50 mph
the speed in miles per minute will be as follows;
1 hr=60 min
thus the speed will be given by:
speed=distance/time
=(50 miles)/(1 hours)
=(50 miles)/(60 min)
=5/6 m/min
thus the distance traveled in 10 min will be:
distance=speed*time
=5/6*10
=8 1/3 miles
1/555 of a mile. I did this by figuring out how many seconds it would take her to walk a full mile and then got the answer for 1 second
