Answer:
-7
Step-by-step explanation:
<em>n = - 1</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6 = - 2(10n + 7)</em>
<em>6 = - 20n - 14</em>
<em>20n = - 6 - 14</em>
<em>20n = - 20</em>
<em>n = - 20 : 20</em>
<em>n = - 1</em>
<em />
<em>6 = - 2(10×-1 + 7)</em>
<em>6 = - 2(-10 + 7)</em>
<em>6 = - 2(-3)</em>
<em>6 = 6 (true)</em>
<em>Good luck !</em>

Answer:
Step-by-step explanation:
Volume=(pi)(radius^2)(height)
Volume=(pi)(5^2)(12)
V=(pi)(25)(12)
V=(pi)(300)
Answer:
Step-by-step explanation:
Given the simultaneous inequality
2x+y<10 ....... 1
2x-4y<8 ....... 2
Subtract both equation from each other
(2x-2x)+(y-(-4y))<10-8
0+5y<2
y < 2/5
y < 0.4
Substitute the given value of y into 1;
2x+y<10
2x + 2/5 < 10
2x < 10 - 2/5
2x < 48/5
10x < 48
x < 4.8
Hence the solution to the inequality expressions is (4.8, 0.4)
