Answer: X = 2 2/3

Step-by-step explanation:

4 5/9 is the same as the sum of 2 1/3 and 5/6 times a number.

Let X be the "number." Translate the sentence:

(4 5/9) = ((2 1/3) + (5/6))*X

"4 5/9 is the same": (4 5/9) =

"as the sum of 2 1/3 and 5/6": ((2 1/3) + (5/6))

"times a number": *X

Put them all together:

(4 5/9) = ((2 1/3) + (5/6))*X

(41/9)-(7/3) = (5/6)X

(41/9)-(21/9) = (5/6)X

(20/9) = (5/6)X

X = (20/9)*(6/5)

X = 120/45

X = 2 30/45 or 2 2/3

The answer is 1 25/57.

Just set the question into an equation:
(2 1/3+ 5/6)x = 4 5/9
(Solve for x and you’ll get 1 25/57).

Answer/Step-by-step explanation:

The length of the boxes and whiskers of a box plot tells us more about the spread the data being represented is and as well as the shape of the spread.

Invariably, if the length of the left box and left whiskers is of the same length as the right box and right whiskers, this implies that the distribution of the data point is close to being symmetric, or approximately symmetrical.

valkas [14]

The measurements of the box actually aren't needed since they already gave you the surface area. Just multiply the given surface area by the price of wrapping paper per square inch: 182.5 x $0.012 = $2.2224. If you round that answer, you'll know that it costs $2.22 to wrap the gift.
