Answer:
The number is 4321
Step-by-step explanation:
Let the number be x
16 2/3% = (16x3+2)/3 % = 50/3 %
50/3 % of X = 72
50/300 x X =72
X=(72 x 300)/50
X=21600/50
X=4321

Answer:
3/4-7/9+2/3=0.63
Step-by-step explanation:
.........
Original Figure:
Length = 15
Width = 5
Height = 10
Volume = Length*Width*Height
Volume = 15*5*10
Volume = 750
New Figure
Length = 3
Width = 1
Height = 2
Each dimension has been divided by 5 (eg: 15/5 = 3)
Volume = Length*Width*Height
Volume = 3*1*2
Volume = 6
The old volume was 750 and it changes to 6
Notice how 750/6 = 125
Which can be rearranged to 750/125 = 6
Answer: if you divide the old volume by 125, then you get the new volume
Note: the new volume is 125 times smaller than the old volume
Put another way, the old volume is 125 times larger compared to the new volume
The fact that 125 = 5^3 is not a coincidence. If you divide each dimension by some number k, then you divide the volume by k^3
Answer:
BADC
Step-by-step explanation:
-4x + 7 
27 Subtract 7
-4x 20 Divide both sides by -4
x 
-5 B
3x - 10 < -25 Add 10
3x < -15 Divide by 3
x < -5 A
5(x - 2) > -15 Use distributive property
5x - 10 > -15 Add 10
5x > -5 Divide by 5
x > -1 D
x - 9 < -10 Add 9
x < -1 C
