Answer:
8
Explanation:
Let's use algebra to solve the problem:
Let x be the number of snowmen built on Tuesday.
On Monday, they built 3 snowmen.
On Tuesday, they built x snowmen.
The total number of snowmen they had after building on Tuesday is 11.
So, the equation representing the total number of snowmen is:
3 (from Monday) + x (from Tuesday) = 11
To find the value of x, we can solve the equation:
3 + x = 11
Subtract 3 from both sides:
x = 11 - 3
x = 8
Therefore, they built 8 snowmen on Tuesday.
