Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33
Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
First, 4d-7=25/4
Then,4d=53/4.
Then you cross multiply, to get 16d = 53. Your final answer is 53/16, or 3 5/16.
Answer:
I can't exactly draw this out on this website, but I can tell you how to do it:
First, solve the inequality so it resembles a function:
7x - y ≥ 14
-y ≥ -7x + 14
y ≤ 7x - 14 (Both side multiply by -1)
Then, graph y = 7x - 14
- Draw a straight line (Don't do the dotted lines because it's not > or <)
- Here's a couple of points to get started: (0, -14), (1, -7)
Finally, because y is less than/equal to 7x - 14, shade in the area under/below the line(where the y-values are smaller).
