Answer:

<u>37.5 parcels </u>in 5 minutes.  Round down to 37, if required for the purpose of the calculation.

Step-by-step explanation:

Let M and K be the rates Michael and Kate can pack parcels, in parcels/minute, or p/m.

M = (10/3)p/m

K = (7/2)p/m

When they work together for 5 minutes, we can calculate the numbers of parcels each pack.

Michael:  ((10/3)p/m)*(5m) = 20 p

Kate:        ((7/2)p/m)*(5m) =  17.5 p

                             Total  =    37.5 parcels

After 4 years eldi will be three times the age he had 10 years ago. Using algebra find the age of eldi
Setler [38]

Suppose that Eldi has x years old now :

x + 4 = 3 × ( x - 10 )

x + 4 = 3x - 30

Add both sides 30

x + 4 + 30 = 3x - 30 + 30

x + 34 = 3x

Subtract both sides x

x - x + 34 = 3x - x

34 = 2x

2x = 34

Divide both sides by 2

2x ÷ 2 =34 ÷ 2

x = 17

_____________________________

Thus Eldi is 17 .
