Daria has 12 to 15 nickels because 3x3=9 but u want to double the amount which would be 12 to 15
B. -3 and 5
constants are the numbers without variables (the letters) and coefficients are the numbers with variables
It would have to be 15 and 8
<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>
