The sign should be flipped to show that the hours of community service are greater than, or equal to 10 hours.
Let L and S be the number of large and small dogs respectively.
L+S=8 so we can say L=8-S
5S+8L=55, using L found above in this equation yields:
5S+8(8-S)=55
5S+64-8S=55
-3S+64=55
-3S=-9
S=3, since L=8-S
L=5
So Ryan walked 3 small dogs and 5 large dogs.
Answer:
y = (10/7)x
Step-by-step explanation:
Ok so this is a hard question but I believe the answer is y = (10/7)x
Answer:
x= -8 y=6
Step-by-step explanation:
Answer:
(2, 8)
Step-by-step explanation:
There are a couple of different ways to do this, but I am going to use substitution since we already have one of those equations solved for y. If y=3x+2, then we can sub 3x+2 in for y in the other equation:
-3x + 2(3x + 2) = 10 and
-3x + 6x + 4 = 10 and
3x + 4 = 10 and
3x = 6 so
x = 2. Now that we know x = 2, we can sub a 2 in for x in either equation to solve for y:
y = 3x + 2 gives us, with the substitution, y = 3(2) + 2 so y = 8. The solution set is (2, 8)
