The sum of twice a number and 13 is 47. Find the number.

17

Step-by-step explanation:

In this problem, the phrase "a number" can be interpreted as a variable.  In this case, let the variable be "x."

Thus, "twice a number" = "2x"

"and 13" = "+ 13"

"is 47" = "= 47"

Thus, the problem is simply 2x + 13 = 47.

Then, simply subtract 13 from both sides to get 2x = 34.

Then, simply divide both sides by 2 to get x = 17.

Because "the number" is "x," the number is 17.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
