Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
Am presuming you are asking for the length of each ribbon in feet.
5 of them = 2 yards.
1 of them = 2/5 = 0.4 yards.
But note 3 feet make 1 yard.
Therefore: 0.4 yards = 0.4 * 3 feet = 1.2 feet.
No they do not. For example, on a number line with the numbers -2 and 2, they are in different locations on a number line. -2 is farther on the left, while 2 is farther on the right. Therefore, opposites do not name the same location on a number line!
