Answer:

<h2>x = 67.5 ft</h2>

Step-by-step explanation:

ΔNPM and ΔABM are similar. Therefore the sides are in proportion:

\dfrac{AM}{NM}=\dfrac{BM}{PM}

We have

AM=71.5\ ft-22\ ft=49.5\ ft\\NM=71.5\ ft\\BM=x\\PM=97.5\ ft

Substitute:

\dfrac{49.5}{71.5}=\dfrac{x}{97.5}       <em>cross multiply</em>

71.5x=(49.5)(97.5)

71.5x=4826.25           <em>divide both sides by 71.5</em>

x=67.5

he city of Metropolita added a new subway station in a neighborhood between two existing stations. After the station was built,
saw5 [17]

Answer:

V= $8

Step-by-step explanation:

Letting V denote the value of an hour,

the annual value of the time savings from the change can be written as

= (5 days/week × 50 weeks/year × .25 hours/day) × V, or 62.5 V per year.

The present value of 62.5 V per year, forever, at a 5% discount rate, is

= 62.5 V / 0.05.

The implication of the change in house prices is that households were willing to pay $10,000 to gain 15 minutes per commuting day, i.e., that the present value of the time savings is $10,000.

Setting 62.5 V / 0.05 = $10,000 and solving gives V = $8

15-20 pleaseee!!!! I really. Red help

15. First Distribute
-6x-4 = 2X + 6
Add 6X on both sides
-4 = 8x+6
Subract 6 on both sides
8x=-10
Divide by 8 on both sides
X = -10/8 = -5/4
16. -13
17. Cross Multiplication
32 = 3X-3
Add 3 on both sides
35 = 3X
Divide by 3 on both sides
35/3 = X
18. Can't see the whole picture
19. Add 7 on both sides
6N = 42. Divide by 6
N = 7
20. 2x+6=-x+1. ---- I cross multiplied
2x+5=-x. ---- I subract 1 on both sides
-3x = 5. ----- Subract 2X
X=5/-3 ---- I divided it by -3
