A.) Equation of Perimeter of a rectangle (P) = 2(l + w)
48 = 2(9 + x)
B.) Solving: 48 = 2(9 + x)
48 = 18 + 2x
2x = 48 - 18
x = 30/2
x = 15
In short, Width would be: 15 inches
Hope this helps!
The equation is a reduction
it’s scale factor is 1/ 2
an algebraic representation for the dilation is written as (x, y) -> (kx, ky), with k being the variable for the scale factor
(2, 6) -> (1/ 2 • 2, 1/ 2 • 6)
So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.
So the equation is

Then we solve by isolating the x. We divide 2.25 both sides then we get
Step-by-step explanation:
circumference of a circle
U = 2 x pi x r
what you know:
U = 13
rearrange and solve for r
U/(2 x pi) = r
