You use a number line to see what is greater and less than.
And use a model to visualize it more.
And they are alike because they can both help in the same way but for different people.
Answer:
-17x
Step-by-step explanation:
(2x^3 - x^2) - (3x^3 - 2x^2)
(8x - 2x) - (27x - 4x)
6x - 23x
-17x
(I haven't seen many questions like this before, but I think that this may be the answer.)
Answer:
Step-by-step explanation:
At the point where Roshonda and James meet each other, they must have covered equal distances.
Let x represent the distance that Roshonda covered while riding from school to home and also the distance covered by James while travelling in a bus from school.
Let t represent the time it took Roshonda to cover x miles.
Distance = speed × time
Therefore
x = 12 × t = 12t
James left school 0.25 hours later at a speed of 35 miles per hour. Time spent by James in covering x miles would be t - 0.25.
Distance covered would be
x = 35(t - 0.25) = 35t - 8.75
Since the distance covered is the same, then,
12t = 35t - 8.75
35t - 12t = 8.75
23t = 8.75
t = 8.75/23 = 0.38 hours
0.38 + 0.25 = 0.63 hours
0.63 × 60 = 37.8 minutes
At about 3:38 pm, they would meet
