Steve exercises by rollerblading. He skates
4 kilometers on Mondays, 5 kilometers on Thursdays, 8 kilometers on Saturdays, and 10 kilometers on Sundays. If he clocked
17 kilometers for the week, on which days did he skate?
Let's assign variables to each day of the week:
Mondays: x
Tuesdays: y
Wednesdays: z
Thursdays: a
Fridays: b
Saturdays: c
Sundays: d
Given that Steve skates 4 kilometers on Mondays, 5 kilometers on Thursdays, 8 kilometers on Saturdays, and 10 kilometers on Sundays, we can set up the following equations:
x + a + c + d = 17
x = 4
a = 5
c = 8
d = 10
Substituting the known values into the equation, we have:
4 + 5 + 8 + 10 = 17
27 = 17
Since this equation is not true, there must be an error in the initial information or calculations.
