100 i think, sorry if I’m wrong lol
Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
2 - (2t + 1) = 4(t + 2)
First you want to distribute the 4 on the right side to everything in the brackets by multiplying both terms by 4
2 - (2t + 1) = 4t + 8
Then you want to add (2t + 1) to both sides
2 = 4t + 8 + (2t + 1)
Now you can get rid of the brackets
2 = 4t + 8 + 2t + 1
Simplify
2 = 6t + 9
Minus 9 on both sides
-7 = 6t
Divide by 6 on both sides
-1.17 = t
Answer:
7 pages
Step-by-step explanation:
Given the total number of pages in the book are 16
The number of pages esteban already read are 9
Let the number of pages left out to read be x
Total number of pages = number of pages read + number of pages to be read
16=9+x
x=16-9
x=7 pages
Therefore There are 7 pages left out to be read.
