Answer:
Option D.
Step-by-step explanation:
The given expression is
We have to write it in the simplified form.
=
= (5.5 - 0.37)×
= 5.13×
Option D will be the answer.
Answer:
The answer is: C. a number.
Step-by-step explanation:
The answer is: C. a number.
That is obtained by clearing the incognite as follows: 5 p = 7; p = 7/5; p = 1.4
Answer: Choice D) ordered pair is not a solution to the second equation
We can see this by replacing x and y with 1 and -4 respectively
2x + y = 4
2*1 + y = 4 .... replace x with 1
2*1 + (-4) = 4 ... replace y with -4
2 - 4 = 4
-2 = 4 .... this equation is false because -2 and 4 are different values
The last equation being false means that the original equation 2x+y = 4 is also false when (x,y) = (1,-4). Therefore, this ordered pair is not a solution to the second equation 2x+y = 4
A solution to the system must make BOTH equations true simultaneously, not just one.
Answer:
D
Step-by-step explanation:
2x + y = 4
If you substitute x = 1, and y = -4, then
2(1) - 4 = 2 - 4 = -2 not 4
