Statements
Reasons
Answer:
The proposition If Y is the midpoint of XZ, then XY = 1/2 XZ is true.
Step-by-step explanation:
We proceed to present the demonstration of the following proposition:
If Y is the midpoint of XZ, then XY = 1/2 XZ.
1) Y is the midpoint of XZ. Given.
2) [tex]XY + YZ = XZ[/tex] Definition of line segment.
3) [tex]XY = YZ[/tex] By 1)
4) [tex]2\cdot XY = XZ[/tex] 3) in 2)
5) [tex]XY = \frac{1}{2}\cdot XZ[/tex] Algebra/Result
Therefore, the proposition If Y is the midpoint of XZ, then XY = 1/2 XZ is true.

A local park currently has 150.04 square meters of grassy area. The members of a community group have proposed the following
changes to the way the park land is used
• Clearing dead trees and shrubs would allow for 37 51 square meters of additional grassy area.
• Removing an unused picnic pavilion would allow for 82.70 square meters of additional grassy area.
• Updating and expanding the playground would reduce the grassy area by 54 19 square meters
How many square meters of grassy area would the park have if all of the community group's proposals were applied?
Answer: they would have 216.06 square meters of grassy area left in the park
Step-by-step explanation: if you start with 150.04 and add 37.51 by removing trees and shrubs you would have 187.55 and then if you added 82.70 more square feet by removing the unused Picnic pavilion you would have 270.25 square meters of grassy area. Then lastly is you update the playground by reducing 54.19 square meters ( 270.25-54.19) you would get left with 216.06 square meters of grassy area :)

4) Choose the correct inequality for this situation.
The Walter family budgets a maximum amount of $124 for a camping trip.
Mr. Walter already spent $40. How many people x can go canoeing if the
cost is $21 per person?
A- 21x + 40 >_ 124
B- 21x + 40 <_124
C- 40x + 21 < _124
D- 21x + 40 > 124
Answer:
B. 21x + 40 ≤ 124
Step-by-step Explanation:
Maximum amount budgeted = $124 (this means they can't spend more than this)
x = number of people
Cost per head = $21
Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:
21x + 40 ≤ 124
(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).

8z - 22 = 3(3z + 11) - z
Answer:
There are no solutions.
Step-by-step explanation:
8z−22=3(3z+11)−z
Step 1: Simplify both sides of the equation.
8z−22=3(3z+11)−z
8z+−22=(3)(3z)+(3)(11)+−z(Distribute)
8z+−22=9z+33+−z
8z−22=(9z+−z)+(33)(Combine Like Terms)
8z−22=8z+33
8z−22=8z+33
Step 2: Subtract 8z from both sides.
8z−22−8z=8z+33−8z
−22=33
Step 3: Add 22 to both sides.
−22+22=33+22

Solve the simultaneous equations 3x- 4y =20 and 4x-2y = 25
Answer:
(6, - [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
Given the 2 equations
3x - 4y = 20 → (1)
4x - 2y = 25 → (2)
Multiplying (2) by - 2 and adding to (1) eliminates the y- term
- 8x + 4y = - 50 → (3)
Add (1) and (3) term by term to eliminate y
- 5x = - 30 ( divide both sides by - 5 )
x = 6
Substitute x = 6 into either of the 2 equations and evaluate for y
Substituting into (1)
3(6) - 4y = 20
18 - 4y = 20 ( subtract 18 from both sides )
- 4y = 2 ( divide both sides by - 4 )
y = [tex]\frac{2}{-4}[/tex] = - [tex]\frac{1}{2}[/tex]
Solution is (6, - [tex]\frac{1}{2}[/tex] )
The solution of the linear equations 3x - 4y = 20 and 4x - 2y = 25 will be (6, -0.50).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The linear equations are given below.
3x - 4y = 20 ...1
4x - 2y = 25
8x - 4y = 50 ...2
Subtract equation 1 from equation 1, then we have
8x - 4y - 3x + 4y = 50 - 20
5x = 30
x = 6
The value of the variable 'y' will be given as,
3(6) - 4y = 20
18 - 4y = 20
4y = - 2
y = - 0.50
The solution of the linear equations 3x - 4y = 20 and 4x - 2y = 25 will be (6, -0.50).

Write the equation of a line in slope-intercept form with a slope of -1 and a y-
intercept of -1.
y = -x - 5
y = -5x - 1
y = -x-1
y= -5x -5
Answer:
y = -x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the slope and y intercept into the equation
y = mx + b
y = -x - 1 is the equation in slope intercept form
Answer:
y = -x - 1
