Answer:
No solution
Step-by-step explanation:
Given two equations are 2x+4y= -8 and 4x+8y= 5
These two lines are parallel They don't have a solution because they do not meet .
Multiply the first equation by 2 we get 4x+8y = -16
the other equation is 4x+8y= 5 clearly these two are parallel .
To prove by elimination method we have subtract those two equations we get 21≠0 which is not possible.
Therefore there is no solution to the given set of equation.
I believe the answer is C. It doesn't make sense to drop an object from -16 feet, and it doesn't make sense to have a -120 in the equation. It should be positive for it to come out right.
Umm subtract 7 from 5 2/7 and u will get 12/7
Therefore, the answer is 12/7
number - N
The sum of a number and three more than twice that number is 27.
N + (2N + 3) = 27
what is the smaller number ?
N + 2N + 3 = 27
3N = 27 - 3
3N = 24
N = 8
Check
N + (2N + 3) = 27 = 8 + (2x8 + 3) = 8 + 16 + 3 = 27
