Answer:
.037 feet
Step-by-step explanation:
perimeter = the sum of all four sides so
perimeter = (4x-9.5) + (9.5x + 10) + (4x - 9.5) + (9.5x + 10) = 27x = 1
therefore x = 1/27 = .037 feet
Try it! Suppose the number I'm thinking of is 49.
The product of 49 and 7 is 343; we subtract 3 from that, obtaining 340.
Divide this 340 by 13: 340/13.
Double this quotient: 680/13
680 + 390
Add 30 to this result: 680/13 + 30 = ------------------ = 1070/13
13
Sadly, this is not 50, as we'd hoped.
Why don't you try doing this yourself? Would you do anything differently from the way I did it?
Its basically the order. The first one is b divided by 10, whereas the second is 10 divided by b. If b was 2, the first one would be .2, where the second one would be 5.
Answer:
100% equals to 1 because 75% = 0.75 so then just add 25% = 0.25 so 0.25+0.75=1
