Let the number of coats Michael has = x

As given, Minnie gathers 3 times as many coats as Michael

So, Minnie has = 3x

Total number of coats = 52

Equation becomes,

x+3x=52

4x=52

x=13

Hence, Michael contributed 13 coats.

lora16 [44]
In order to answer this question let's suppose,
Joe is x miles from the beginning and y miles from the end. These assumptions are necessary to answer further:

Now,
x=2y
x+y=30
plugging in x=2y in the above equation
2y+y=30
3y=30
y=10

Hence, according to our calculations, Joe has to hike 10 miles further
