Second option since its a sun moon and earth model
Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.
Answer:33/9
Step-by-step explanation:
Log10(x+3)-Log10(x-3)=1
Log10((x+3)/(x-3))=1
(x+3)/(x-3)=10^1
(x+3)/(x-3)=10
Cross multiply
x+3=10(x-3)
Open brackets
x+3=10x-30
Collect like terms
10x-x=30+3
9x=33
Divide both sides by 9
9x/9=33/9
x=33/9
So, to find the volume of just the cement part, you need to find the volume of the whole shape, then find the volume of the garden. then subtract them to find the volume of just the cement sidewalk.
volume of garden: 16 x 6 x 1 (l x w x h)= 96 ft3
volume of whole: length=16+4+4=24, width=6+4+4=14, height=1
you have to add 4 to each sides of the length and width to get the entire length.
volume of whole=24 x 14 x 1=336 ft3
now subt.
336-90=246 ft3 would be the volume of the cement walkway.
