Answer:
<h2>y = 64</h2>
Step-by-step explanation:
Answer:he first step in a problem like this (after sketching the problem out for yourself, which very often helps) is to assign variables. Let's call the length x, and the width y.
There are two sections that are y long, and one that's x long. Adding up the total length of the fence, then, gives us x + y + y, or x + 2y, which should be equal to 44, since that's how much fence we have. Our first equation is thus
x + 2y = 44
Our second equation, since the length is supposed to be twice the width, is x = 2y.
This is enough to solve. We can substitute this equation for x into the first equation to get
2y + 2y = 44
4y = 44
y = 11
And then x = 2(11) = 22
So the length of the fence is 22, and the width (though they don't actually ask for it) is 11.
Check the answer: 22 + 11 + 11 is 44, as we want, and 22 is twice as great as 11, as we want. So the answer is valid.

Answer:
-13
Step-by-step explanation:
-21 = k - 8
so we need to get k by itself so we will add 8 to both sides
-21 (+8) = k - 8 (+8)
-13 = k

<em>Comment on the example</em>
"Copy and paste" does not always work well on Brainly, especially when the characters being copied are not text characters. Many fractions get mangled in the process.
We suspect you intend ...
(1/3)/(4/7) = (1/3) ÷ (4/7)
In typeset form, this might be ...
___
Please note that the symbols "/" and "÷" and the word "over" are generally taken to mean exactly the same thing.* When math operations are involved in numerators or denominators, generally you need to enclose those numerators and denominators in parentheses.
1/3÷4/7 = 1/(3·4·7) = 1/84
(1/3)÷(4/7) = (1/3)·(7/4) = 7/12
___
* Some web sites treat them differently. Sometimes "÷" is taken to mean "the quantity everything that comes before the symbol '÷' divided by the quantity everything that comes after the symbol". Sometimes the word "over" is intended to mean the same thing. This usage for ÷ and "over" is non-standard, so it is best to use parentheses to clarify intent.
