I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250
250+120=370!!
answer : 370 kilometers per hour
Step-by-step explanation:
They are parallel.
Parallel lines have the same slope.
for the line y = -2x + 1 the slope is -2 and when we put the line 2x + y = 5 in general equation it will be y = -2x + 5, and it's slope is also -2.
Therefore, the lines are parallel

Answer:
<h2>The answer is x = y = 10.</h2>
Step-by-step explanation:
It is given that, .
Another equation is given by, .
Putting the value x = 2y - 10, in the second equation, we get .
