Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
Step-by-step explanation:
3(2x+5)-7=2(4x-6)
6x+15-7=8x-12
6x+8=8x-12
8=2x-12
-4=2x
x=-2
X= unknown distance
7'2" + 41'6" + x = 61'6"
48'8"+x=61'6"
x=61'6"-48'8"
x=60'18"-48'8"
x = 12'10" 12 ft. 10 in.
Therefore the distance of the house from the other side of the lot is 12 ft 10 inches.<span>
