Answer:
49
Step-by-step explanation:
x + 100 + 31 = 180
x + 100 + 31 - 100 - 31 = 180 -100 -31
x = 49
If

then by this definition,
g(0) = 3 … … … (since -1 < 0 < 2)
and
g(1) = 3 … … … (also because -1 < 1 < 2)
Arithmetic
Recursive: f(n)=(n-1) + 3 f(1)= 5
Explicit: f(n)= 5+3(n-1)
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Hope this helps :D
