<h2>720 I'm sure that's answer</h2>
Answer: c or .25
Step-by-step explanation: 3/12= .25
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- 4x + 8y = 20
- -4x + 2y = -30
<u>Adding</u><u> the</u><u> equations</u><u> </u><u>:</u><u>-</u><u> </u>
10y = -10
y = -1
<u>Put </u><u>it </u><u>(</u><u>i)</u><u> </u><u>:</u><u>-</u><u> </u>
4x - 8 = 20
4x = 20 + 8
4x = 28
x = 28/4
x = 7
I think the point (4,60) represent the velocity
as the velocity at this point = distance / time
so v= 15 km/h
