Answer:
Step-by-step explanation:
Vertical angles are congruent.
8x = 2x +30
6x = 30 . . . . . . subtract 2x
x = 5 . . . . . . . . divide by 6
__
60y -40 = 40y +20
20y = 60 . . . . add 40-40y
y = 3 . . . . . . . .divide by 20
_____
<em>Check</em>
The 'x' angles are 8x° = 8·5° = 40°.
The 'y' angles are (40y+20)° = (40·3+20)° = 140°.
The angles are supplementary, as they are supposed to be.
Appreciation rate = 1.2% = 0.012
Let it take n years
300000^0.012n = 350000
taking log
0.012n * log(300000) = log(350000)
0.012n * 5.4771 = 5.5440
0.0657252 n = 5.5440
n = 84.35 years
2017 + 84.35 = 2101.35
It will be worth $350,000 in 2101
Answer:
5 meters
Step-by-step explanation:
The perimeter of a rectangle can be expressed as 2l+2w.
2l+2w=50
l=w+15
Substitute:
2(w+15)+2w=50
2w+30+2w=50
4w+30=50
4w=20
w=5
