I promised myself I would sit down and write an entry when I got done with my Algebra homework.
However, I can’t seem to finish it. One problem I just gave up on, and will ask the Instructor tomorrow.
The other one, maybe you can help me with.
It is dear to my heart, because I have been known to crochet yards of lace.
To trim the edges of a rectangular tablecloth, 42 feet of lace are needed. The length of the tablecloth is exactly one-half its width. What are the dimensions of the tablecloth?
I peeked back at the answers, and once I know that, it all makes sense. I cannot figure how it comes about.
formula: the perimeter = 2 times length plus 2 times width
Answer: 7 feet by 14 feet ( length = 7 feet; width = 14 feet)
I asked the Instructor this morning about the formula.
I cannot write all the symbols but it goes something like this
P = 42
x = biggest number because it doesn’t matter where the numbers fit, they are multiplied the same
2(x) + 2 (1/2 x) = 42
2 x + x = 42
3x = 42
divide each side by 3
x = 14
1/2 x = 7
Whew! crocheting the lace is easier…..
