Answer:
32.2 is your answer for c
Step-by-step explanation:
Note the equation:
c - 23.7 = 8.5
Note the equal sign. What you do to one side, you do to the other. Isolate the c. add 23.7 to both sides
c - 23.7 (+23.7) = 8.5 (+23.7)
c = 8.5 + 23.7
Simplify.
c = 32.2
32.2 is your answer for c

The diagonals of a square are perpendicular.
Step-by-step explanation:
Answer: In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions
Step-by-step explanation:A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
