Answer:
2.40G + 1.20C ≤15
Step-by-step explanation:
The inequality function is
Given that
The cost of goat milk for each liter is $2.40 = G
And, the cost of the cow milk for each liter is $1.20 = C
Now the equation would be
2.40g + 1.20c
Now this must be lower or equal than $15
So, the inequality function would be
2.40G + 1.20C ≤15
hence, the inequality function is 2.40G + 1.20C ≤15
Answer:
C
Step-by-step explanation:
I think it’s C because under the numbers it says pets they own so the x has to be the fourth graders
We know that
speed=distance/time
solve for time
time=distance/speed
in this problem
<span>Marco runs at a rate of 6 miles per hour.
</span><span>Fernando funs at a rate of 7.2 miles per hour
Difference=7.2-6=1.2 miles/hour
so
speed=1.2 miles/hour
distance=0.3 miles
time=?
</span>time=distance/speed-----> 0.3/1.2-----> 0.25 hour-----> 0.25*60=15 minutes
<span>
the answer is
0.25 hour (15 minutes)
Alternative Method
Let
x---------> Fernando's distance when Marco is 0.3 miles apart
</span>Fernando funs at a rate of 7.2 miles per hour
<span>for distance =x
time=x/7.2------> equation 1
</span>Marco runs at a rate of 6 miles per hour.
for distance=x-0.30
time=(x-0.30)/6------> equation 2
equate equation 1 and equation 2
7.2*(x-0.3)=6x-----> 7.2x-2.16=6x
7.2x-6x=2.16------> x=2.16/1.2-------> x=1.8 miles
time=x/7.2-----1.8/7.2=0.25 hour
1/3 = 4/5
2/3 = 4/5
3/3 = 4/5
-----------------
12/5 = 2 and 2/5 of an hour
2 hours and 24 mins
