Answer:
r = -1 9/20
Step-by-step explanation:
-2 1/4 = r - 4/5
Switch sides:
r - 4/5 = -2 1/4
Add 4/5 to both sides.
r = -2 1/4 + 4/5
Change the mixed numeral into a fraction:
r = -9/4 + 4/5
The LCD is 20.
r = -45/20 + 16/20
r = -29/20
r = -1 9/20
Answer:
The rectangle has a width of 18 inches and a height length of 8 inches.
Step-by-step explanation:
The perimeter of a rectangle is described by the equation:
where <em>l</em> is width, <em>h</em> is height, and <em>p</em> is perimeter.
We're also told that the total perimeter is 52 inches.
We're also told that the length is six inches less than three times the width. We can express that as .
We can plug that definition of w into the perimeter equation to find the length:
Now we can take that and the given perimeter, and substitute those into the perimeter equation to find the width:
So the width is 18
