The intensity level is hard and for the first part, it’s 168. and something. Sorry that’s all I figured out I’m not too smart :/
"Half of a number decreased by 27" can be displayed as:
<u>1/2x - 27</u>
Answer:
-4/7 is the smallest. then it's -1/19 and then finally it's 7/4
The relationship between x and y is represent as:
Since, the relationship is linear.
The standard form of equation of line is:

Consider any two set x and y values from the given relationship.
Let (-2, 10) and (-1,7.5)


The equation of the linear relationship between x and y is:
y = -2.5(x + 2) + 10
Now, to check that the point (9, -17.5) lies on the represented relationship between x and y
Substitute x = 9 and y = -17.5 in the equation y = -2.5(x + 2) + 10
y = -2.5(x + 2) + 10
-17.5 = -2.5(9 + 2) + 10
-17.5 = -2.5(11) + 10
-17.5 = -27.5 + 10
-17.5 = -17.5
Thus, LHS = RHS
Hence the point (9, -17.5) lie on the given linear relationship between x and y.
Answer: The point (9, -17.5) lie on the given linear relationship between x and y.
First, we need to get the total area of the rectangular pool.
Area = l * w
Area = 20 ft * 50 ft
Area = 1000 ft^2
Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.
Area = l * w
456 = l * 20
l = 456 / 20
l = 22.8 ft.
So the walkway is 22.8ft wide.
