Is Char right?
From the homework problems above, there are 5 mathematical problems
So:
Chad's claim that he had 5 equations.
A mathematical expression is an equation if it has an = sign
So for Chad's claim to be correct; at least 4 of the mathematical problems must have an = sign
By the explanation done above, we have the following observations
-> No Equation
-> Equation
-> No Equation
-> No Equation
-> Equation
Apparently, only 2 of the 5 problems are equation.
Hence, Chad's claim is incorrect.
