Answer:
3.53 km
Step-by-step explanation:
Let third day be X:
Second day: X - 0.98
First day: X - 0.98 + 1.37 = X + 0.39
X + X - 0.98 + X + 0.39 = 10
3X = 10.59
X = 3.53 kn
Answer:
k = 18
when x = 4, y = 3, z = -24
Step-by-step explanation:
x = k * y * z
Find k when x = 4, y = 3, and z = 24
4 = k * 3 * 24
4 = k * 72
4 = 72k
k = 72/4
k = 18
find z when x = -3 and y = 4
x = k * y * z
-3 = 18 * 4 * z
-3 = 72 * z
-3 = 72z
z = 72/-3
z = -24
