Answer:
x=0
Step-by-step explanation:
7/2x+6/4x=5/4x
7/2x=5/4x-6/4x
7/2x=-1/4x
7/2x-(-1/4x)=0
7/2x+1/4x=0
14/4x+1/4x=0
15/4x=0
x=0/(15/4)
x=0
78 / 3 3/4 =
78/1 / 15/4 =
78/1 x 4 /15 = 312/15 = 20.8
20 pieces 3 3/4 inches long can be cut
Off the top of my head i could not tell you an accurate answer
For a given girth, the largest area will be that of a square. Then for some length x, the volume will be
.. V = x((108 -x)/4)^2
.. = (1/16)*x*(108 -x)^2
The largest volume will be found where the derivative of this with respect to x is zero.
.. V' = (1/16)*((108 -x)^2 -2x(108 -x))
.. 0 = (108 -x)(108 -x -2x)
.. x = 108 or 108/3 = 36
The dimensions of the largest package that can be mailed are
.. 36 inches in length and 72 inches in girth
The volume of that package is 11,664 in^3.
Answer:
50
Step-by-step explanation:
Let a = number of balls in bag A.
Let b = number of balls in bag B.
a = 1.2b
a - 5 = b + 5
1.2b - 5 = b + 5
0.2b = 10
b = 50
Answer: 50
