Karo-lina-s [1.5K]

Answer:

$3+3i$

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two complex numbers (a+bi) and (c+di) points is equal to

$(\frac{a+c}{2})+(\frac{b+d}{2})i$

we have

(1+9i) and (5-3i)

substitute the given values

$(\frac{1+5}{2})+(\frac{9-3}{2})i$

$3+3i$

Pls help me asap stuck on this

mylen [45]

Answer:

Step-by-step explanation:

Morning: $4\frac{7}{8} +1\frac{2}{3} =\frac{39}{8} +\frac{5}{3} =\frac{117}{24} +\frac{40}{24}=\frac{157}{24}$

Afternoon: $3\frac{5}{6} +2\frac{7}{12} =\frac{23}{6} +\frac{31}{12} =\frac{92}{24} +\frac{62}{24}=\frac{154}{24}$

Therefore, the hiker's hiked $\frac{3}{24}$ more in the morning than in the afternoon.
