Answer:
49 blue marbles
Step-by-step explanation:
From the question we are given;
- Total number of marbles = 58
- Blue marbles are 4 more than 5 times the red marbles
We need to determine the number of blue marbles;
Assuming the number of red marbles is x
Then, blue marbles will be 5x + 4
Therefore;
x + 5x + 4 = 58
6x + 4 = 58
6x = 54
x = 9
5x + 4 = 5(9) + 4 = 49
Therefore, the red marbles are 9 while the blue marbles are 49
Hence there are 49 blue marbles

Step-by-step explanation:
going around the field one time is walking all 4 sides.
so, 4×13 m
going around the field 5 times is walking all 4 sides 5 times.
that means
5×4×13 m = 20×13 = 260 m
Okay I know how to do this, first set it up as
161 X
-----=------
575 100
Then cross multiply
