Answer:
14
Step-by-step explanation:
Given that:
Cost of purchase and installation = 5323.50
Cost per window = 230.25
Cost of installation = 2100
Hence,
Total purchase cost of windows alone :
5323.50 - 2100 = 3,223.50
Therefore, the number of windows purchased is :
(Total purchase cost of windows alone / price per window)
(3,223.50 / 230.25)
= 14
Hence, 14 windows was purchased

Answer:
C
Step-by-step explanation:
distributive property of equality
1/2(10x-4) = 5x-2
combine like terms
4x+5x-2=6-----------4x and 5x are the like terms
9x-2=6
addition property of equality
9x-2+2=6+2
9x=8
Division property of equality
9x=8-----------------------dividing both sides by 9
9x/9=8/9
x=8/9

See descriptions below.
Step-by-step explanation:
To construct a perpendicular bisector, draw a line segment. From each end of the line segment, draw arcs above and below which intersect from each side. Be sure to maintain the same radius on each. Where the arcs intersect above and below, mark points. Connect these two points. This is a perpendicular bisector.
To prove theorems about parallel lines, use angle relationships. For instance, when two parallel lines are cut by a transversal, specific angle are congruent. When these relationships are congruent, you must have parallel lines:
- Alternate Interior
- Alternate Exterior
- Corresponding Angles
- Same side interior add to 180
