On a number line, the coordinates of J, K, L, M, N are −10.5, −4, −1, 1.5, 4 respectively. Find the lengths of the two segments. Are they congruent? JL¯¯¯¯¯ and KN¯¯¯¯¯¯
A. JL = 12, KN = 8; no
B. JL = 12, KN = 8; yes
C. JL = 9.5, KN = 8; yes
D. JL = 9.5, KN = 8; no

Long division setup showing an incomplete calculation. 12 is in the divisor, 6839 is in the dividend, and 5 hundreds and 6 tens is written in the quotient. 6000 is subtracted from 6839 to give 839. an unknown value represented by a box is being subtracted from 839. what number should be placed in the box to complete the division calculation?
