The equation can be modeled as
X + X + (X+4) = 61
X is used for all because they are all the same number and can be given the same variable
The third is given plus four so we can use a common variable
3x + 4 = 61
3x = 57 (subtracted four)
x = 19 (divided by three)
Solving for third side so x + 4
The third side is 23 inches
That's the Law of Syllogism
Let's go through the list.
Substitution property
This is a very general rule in math that allows us to substitute things that are equal for one another.
Symmetric property
Abstractly, a relation is a set of ordered pairs. A relation R is symmetric when
Usually we talk about equality or congruence being symmetric: a=b implies b=a.
Law of Syllogism
That's a rule of logic that says if <em>a implies b</em> and <em>b implies c</em> then <em>a implies c. </em> Again it's a very general rule that applies across all mathematics.
Law of Detachment
This one is more commonly known as modus ponens. It's a general rule of formal logic, applying across all mathematics.
If we know two propositions <em>p implies q</em> and <em>p</em> then we can conclude a third proposition, <em>q.</em>
Formal logic acts at a purely syntactic level. It is a mechanistic pushing around of symbols on the page. Nonetheless, in the real world when the premises of an argument are true, the conclusions drawn as a result of formal logic will be true as well.
Answer: Law of Syllogism
This one above lol ,......................m
Answer:
y=x^2-5x+4 i am not sure but a im try
59.96.
If you distribute 4 to 14.99 then you get the answer above.
