Answer:
2
Step-by-step explanation:
7x - 2x = 13 - 3
5x = 10
x = 2
Since you are solving for diameter, and the equation is given to you, just isolate the variable for diameter (d).
(C)/π = (πd)/π
d = C/π is your formula you will use.
Plug in 56 for C
d = 56/π
d = ~17.825

When functions are defined by more then one equation, they are called piecewise defined functions
So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5
