Answer:
Step-by-step explanation:
Given
See attachment
From the attachment, we have:
First, we need to calculate length LM,
Using Pythagoras theorem:
Collect Like Terms
Solving (a):
Substitute values for MN and LN
Solving (b):
Substitute values for LM and MN
Solving (c):
Substitute values for LN and LM
Solving (d):
Substitute values for LM and LN
So the total amount of marbles is: 20+12=32
there are 20 pink marbles
20/32 = 10/16 = 5/8 (simplified)
