The answer is -49 because you multiply by 7.
That would be 13/10 or 1 3/10
Since the distance is 560 miles and the bus goes 268 miles per hour, the answer can be given as:
If 268=1 hour
560=?
560/268*1 hour =2(rounded to nearest ones)
Therefore it will take the train approximately 2 hours to travel between both cities.
first, spread the parenthesis. y+2=1/2x-1.5
second, add 1.5 to both sides. y+3.5=1/2x
third, multiply by 2. 2y+7=x
if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5
hope this helps!
ANSWER: x=2y+7 or y=x-3.5
