We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
Answer:
the median is the middle number.
and the mode is the number that occurs most.
so if we put everything in order
53, 53.5, 54, 54.5, 54.5, 55, 57
so the mode would be 54.5 cause it occurs twice
and the median would be somewhere in between 54 and 54.5
Answer:
15 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (9, 10)
d = 
= 
= 
= 
= 15
So first let’s combine like terms and add 4/9x and 1/5x together to get 29/45x =58. Next, multiply 58 by 45/29 to isolate x, so x=90
