A. A sequence of statements that demonstrates the truth of an assertion.
Step-by-step explanation:
Mathematical proofs are a series of statements in order that help prove that something is true.
Proofs do not prove that something is false, they are not always 3 parts, and they are not in any order, because they have to be in an organized sequence.
So, A is correct.
You put the decimal over a number with one more digget. if the number was .66 you would make it 66/100 if the number was .777 you would make the fraction 777/1000
a=6, b=2
Step-by-step explanation:
Use simplification into substitution



We can now plug this value of <em>a</em> into the second equation.

Get rid of fractions in the numerators and/or denominators

Then we can match the denominators

Combine

Divide both sides by three

Get rid of fractions

Single out <em>b</em>


Now we can plug it into the equation



Now we can check it;
