I believe the answer is D.) 360
<u>To make this problem solvable, I have replaced the 't' in the second equation for a 'y'.</u>
Answer:
<em>x = -9</em>
<em>y = 2</em>
Step-by-step explanation:
<u>Solve the system:</u>
2x + 3y = -12 [1]
2x + y = -16 [2]
Subtracting [1] and [2]:
3y - y = -12 + 16
2y = 4
y = 4/2 = 2
From [1]:
2x + 3(2) = -12
2x + 6 = -12
2x = -18
x = -18/2 = -9
Solution:
x = -9
y = 2
Answer: 324 trees
Explanation: (cross multiply and divide)
In a fraction put x over 450 then next to it put 72 over 100 hundred
Cross multiply
72x450=32,400
100x= 32,400 (Divide each side of equation by 100)
X= 324
-OR- Just multiply 450 by .72
Either way you get the same answer. Hope this helped:)
The answer would be ≈1948.73 in. The formula to solve would be:
A = 6 a h + 3 √3 a²
I hope this helps love! :)
