Answer:
x+7y = -77
Step-by-step explanation:
multiply both sides by 7 to get rid of denominator
7y = -x-77
now move x term to other side
x+7y = -77
The display after stacking of 6 layers of cube is 30 inches high.
Step-by-step explanation:
The volume of cubic box used by Abbey= 125 inch³
Total no of layer he has in display= 6
Height of the display-
We know that the volume of the cube is a³
Where a is the side of the cube
Hence to find the side of the cubic box we need to find the cube root of the volume i.e. ∛125
Hence the side of each cube is 5 inch. Since all the sides for cube are equal hence the height would also be 5 inch
The total height of the display would be 6*5= 30 inches
Answer:
length = 48 feet , width = 32 feet
Step-by-step explanation:
Using
2W + 2L = 160 with W = L - 16 , then
2(L - 16) + 2L = 160 ← distribute and simplify left side
2L - 32 + 2L = 160
4L - 32 = 160 ( add 32 to both sides )
4L = 192 ( divide both sides by 4 )
L = 48
Substitute L = 48 into W = L - 16
W = 48 - 16 = 32
Thus length = 48 feet and width = 32 feet

To answer this question we will have to understand the nature of 
.
can be rewritten as: 
. Now, 
is an irrational number and thus any of the four operations of addition, multiplication, subtraction or division placed anywhere between any of these terms will always result in an irrational number.
The only way irrational numbers can be made rational is by dividing or multiplying the given irrational number by the same irrational number.
