<h3>
Answer: 40 inches</h3>
==========================================================
Explanation:
- x = first piece
- 2x = second piece, since its twice as long as the first
- 5x = third piece, since its five time as long as the first
x is some positive real number, and the units of each are in inches.
Add up the smaller pieces and we should get 64 inches back again
x+2x+5x = 64
8x = 64
x = 64/8
x = 8
The first piece is 8 inches long.
2x = 2*8 = 16 is the length of the second piece (in inches)
The third piece is 40 inches because 5x = 5*8 = 40
--------
Summary:
first = 8 inches
second = 16 inches
third = 40 inches
Check: 8+16+40 = 64, which confirms the answer
Answer:
-0.555
Step-by-step explanation:
-2/3÷12
=-2/3÷12×3/1×3
=-2/3÷36/3

I got this answer but don't know how did you got -8?!
Answer:
3.) D
4.) B
Step-by-step explanation:
5
Step-by-step explanation:
AB=CD (Opposite sides of a parallelogram are equal)
11x-13=42
11x=42+13
11x=55
x=55/11
x=5
A general formula for the volume of a container is V = length x width x height (other words may be used in place of the three given).
3. 900 in^3, the fourth option
V = 20 x 15 x 3
V = 900 in^3
4. 288 in^3, the third option
V = 6 x 6 x 8
V = 288 in^3
Hope this helps!! :)
