13x + 13 + 2x = 2
15x + 13 = 2
15x = -11
Answer:
5 apples
Step-by-step explanation:
Solution,
4 apples are required for a pie tin with a diameter of 8 inches
For 1 inch of the pie tin 8/4=2 apples are required.
For 10 inches 10/2=5 apples are required.
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:
x=0
Step-by-step explanation:
-2x+9=9
-2x=9-9
-2x=0
x=0/-2
x=0
7x - (3x + 7)....not simplified
7x - 3x - 7 =
4x - 7....simplified
