Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
10 men can survive for 24 days with 15 cans of ration
so , 1 man can survive for 1 day with 15/(10*24) cans of ration
so, 8 men can survive for 36 days with (15*8*36)/240 = 18 cans of raion
X=3
91 + x^2
91 + 3^2
91 + 9
91 + 9 = 100
It's 6!=720.
The formula for circular permutation is given by (n-1)!
This is because of the fact that in a circular setting if you move each of the person one way right or left, you still get the same arrangement, and we can do so n times until we get back to the first arrangement.
Answer:
5 times
Step-by-step explanation: 71 divided by 14 equals 5
