I think it would be (8)(-1) = -8. by adding the two equations you get 2x = 16 so x = 8 then y = 7 - x = -1. Therefore xy = -8.
Hope that helps
Answer:
6 miles
Step-by-step explanation:
From the above question:
Stan ran 4 and StartFraction 7 Over 10 EndFraction miles
The number of miles stan ran =
4 7/10 miles
We are also told that this number of miles was 1 and StartFraction 3 Over 10 EndFraction fewer miles than Matt ran.
Let the number of miles Matt ran = m
Hence,
4 7/10 miles = m - 1 3/10
m = 4 7/10 + 1 3/10
m = (4 + 1) + ( 7/10 + 3/10)
m = 5 + (7 + 3/10)
m = 5 + (10/10)
m = 5 + 1
m = 6 miles
Therefore, the number rod miles Matt ran was 6 miles
8(5) - 4y = 39
40 - 4y = 39
-4y = -1, y = 1/4
Solution: y = 1/4
Answer:
30 miles
Step-by-step explanation:
average= sum of miles ÷ days to cover = 30
