Answer:
10
Step-by-step explanation:
AB + BC = AC and AC = 14
x + 15 + 2x + 32 = 14 add like terms
3x + 47 = 14 subtract 47 from both sides
3x = -33 divide both sides by 3
x = -11 now the length of BC
2x + 32 replace x with -11
2*(-11) + 32 = 10
2n + 32 = 4n - 2
-2n = - 34
n = 17

I can't edit pictures for you so as a result I can't answer it. But label those numbers on the x line and that will be your answer. And OMG your laptop is torn up I tell you TORN.
It took both 2.5 hours to be 110 miles apart
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance / time
Since both steamers is travelling at 22 mph. therefore they cover the same distance at the same time. For them to be 110 miles apart, they need to each have covered 55 miles in the opposite direction
22 = 55/time
time = 2.5 hours
Therefore after 2.5 hours they would have covered 55 miles each therefore being 110 miles apart.
