Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
Step-by-step explanation:
200 + 100 + 150 + 200 +150 = 800 m in total
8 min in total
you are going 100 m a minute or 6000 m an hour
Answer:
the answer is y=-0.556·x+7
$92,28-$18=$74.28
$74.28<span>÷$0.06= 1238minutes</span>
