<span>The student apparently added numbers without taking into account direction. They seem to have added 15 and 25 and divided by 2 to get the horizontal component of the middle stop when they should have added 15 and -25 and divided by 2. A similar mistake was made on determining the vertical component. The middle stop should have been calculated as 5 blocks west and 7 blocks south of the central station. So your answer is C.</span>
Answer: the only answer is d
Step-by-step explanation:
<span>-403 - -177
Since two negative signs equal one positive sign, convert - -177 to +177
-403+177
I would make -403 into 403 and subtract 177 from it. Then at the end, put the negative sign next to the result.
226
Put the negative sign next to 226 since it was removed earlier from 403.
Final Answer: -226</span>
