Given:
perfect score- 100
number of questions of the test- 25
worth of each question- 4 points
Fred's score- 84
n- number of questions Fred had answered incorrectly.
solution:
solve for n
division sentence: (100 ÷ 4 ) - ( 84 ÷ 4 ) = n
(100 ÷ 4 ) - ( 84 ÷ 4 ) = n
25 - 21 = n
4= n
therefore, Fred had answered 4 test questions incorrectly.
To solve this, subtract 6 from both sides of the greater than sign to get..
x is greater than -4
I think the answer is -6 because you have to use slope-intercept form y=mx+b
Ok I think this may be right but I hope this helps!
