Answer:
Step-by-step explanation:
Use ratios to find x and y, then find AB and GH, them sum up the lengths.
<u>Find x:</u>
- 12/15 = x/10
- x = 12*10/15
- x = 8 in
<u>Find y:</u>
- 12/15 = 16/y
- y = 15*16/12
- y = 20 in
<u>Find AB:</u>
<u>Find GH:</u>
<u>Find the perimeter:</u>
- P = 6 + 15 + 20 + 10 + 37 + 8 + 16 + 12 = 124 in
Answer:
r - 24
Step-by-step explanation:
[X · Y - Z] = (r + 2)(2r - 9)] - (r^2 + 17r + 30)
= (2r^2 + 4r - 9r - 18 ) - r^2 - 17r - 30
= 2r^2 - 5r - 18 - r^2 - 17r - 30
= r^2 - 22r - 48
= (r +2)(r - 24)
so
[X · Y - Z] / X
= [(r +2)(r - 24)] / (r + 2)
= r - 24
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
