Answer:
-g/3+1/3
Step-by-step explanation:
Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.
N.A = 30 (1.20)^t
N.B = 45 + 3(t)
t = 5
N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
<span>N.B = 45 + 3(5) = 45 + 15 = 60</span>
Answer:
$14.07
Step-by-step explanation:
100 - 15 = 85
You change this into a multiplier 0.85.
18 x 0.85 = 15.30
100 - 8 = 0.92
0.92 x 15.30 = 14.07
<u> 3x + y = 25</u>
To solve for 'y' ...
Subtract 3x from each side: <em> y = 25 - 3x</em>
===========================================
<u>3x + y = 25</u>
To solve for 'x' ...
Subtract 'y' from each side: 3x = 25 - y
Divide each side by 3 : <em>x = (25 - y) / 3 </em>
