Answer: 1728
Step-by-step explanation: You multiply 12 times 12 because we have to find how many items are in a 12 dozen first which is 144 because there are 12 items in one dozen. We already know that there are 144 items in 12 dozens and there are 12 dozens in a gross, which is 144 items in total. Now we have to multiply 144 times 12 to find how many items are in a great gross. 144 times 12 is 1728.
Answer:
The correct length is <em>34 feet</em>.
Step-by-step explanation:
Let us assume that the wall created is a rectangle <em>ABCD</em> as shown in the attached image.
We know that opposite sides of a rectangle are equal.
<em>Perimeter</em> of a <em>closed figure is calculated by adding all the sides of the figure</em>.
Here, from the figure, the perimeter is : AB + BC + CD + DA
AB and CD are equal to length.
BC and DA are equal to width.
So,
Here, we are given that <em>perimeter </em>is 100 feet and <em>width</em> = 16 feet
Putting values in equation (1):
Hence, length is 34 feet.

Step-by-step explanation:
There are several ways this can be accomplished. Students could survey every 20 students until they've asked 100 students, or they could ask 1 or 2 people at each cafeteria table during each lunch, just for examples.
Answer:
x = 2
Step-by-step explanation:
7(3x + 5) - x = 75
1. Distributive property
multiply 7 by whatever is in the parenthesis
7*3x + 7*5 - x = 75
21x + 35 - x = 75
2. Combine like terms
21x - x = 20x
20x + 35 = 75
3. Subtract 35 on both sides
20x + 35 - 35 = 75 - 35
20x = 40
4. Divide both sides by 20 since u want to isolate the variable
20x/20 = 40/20
x = 2
And thats ur answer
Hope this helped!
