y2 - y1 / x2 - x1 = slope
Answer: The number is: "2" .
_______________________________________________________
The expression is: 2 − (½)x = (½)<span>x ;
</span>→<span> in which "x" is the "unknown number".
</span>_______________________________________________________
Explanation:
______________________________________________________
Given:
_________________________________________________________
"Two decreased by a half of a number is one-half<span> of the number" ;
Let "x" represent the "unknown number" for which we wish to solve;
Write the expression as:
_________________________________________________
" </span>2 − (½)x = (½)x " .
_________________________________________________
Note: Add "(½)x" to EACH SIDE of the equation:
_________________________________________________
2 − (½)x + (½)x = (½)x + (<span>½)</span>x ;
to get:
_________________________________________________
→ 2 = 1x ;
↔ 1x = 2 ;
↔ x = 2 .

<span>An
algebra test had two parts.
=> Part I had 40 problems
=> and part II had 60 problems.
Bernard got 80% of the problems on part I correct and 90% of the problems on
part II correct. What was the total number of problems that Bernard got correct
on the test.
Part 1
=> 40 problems and Bernard was able to answer correctly that 80% of it
=> 40 * .80 = 32 questions are correct
Part 2
=> 60 problems and Bernard was able to answer correctly the 90% of it.
=> 60 * .90 = 54 questions got correct answers.</span>
