7*4=28
7-4=3
so the width is 4 feet and the length is 7 feet
3x92 = 276 (first 3 exams)
average of at least 90 (90 x 4 = 360)
360 - 276 = 84
Answer
<span>she needs to score at least 84 on the fourth exam </span><span>in order to guarantee a final average of at least 90</span>
<span>The original statement would remove the two "not" values from the converse, giving "If it is April 17th, then it is Matt's birthday." Similarly, to find the inverse of the original conditional, simply flip the two statements. As such, the inverse would read "If it is Matt's birthday, then it is April 17th."</span>
