Answer: 22
Step-by-step explanation:
Use pi=3.14
pi * d
3.14 * 7
21.98 = 22
Option B is correct. The statement that is true about the values we have been given here is that They are the only values that make both equations true.
<h3>How to solve for the equations</h3>
We have been given two equations
The first equation is
4y-3x=16
We have to plug in the values (-5, 0.25) in this equation
4(0.25) -3(-5) =16
Then we have
1 + 15 = 16
Hence 16 = 16 This satisfies the equation.
In the second equation we have to follow the same step
-x-8y=3
Such that
-(-5)-8*0.25 = 3
5-2 = 3
3 = 3 This also satisfies the equation.
Therefore the correct answer option is B
<h3>Complete question</h3>
a. They satisfy equation 8 but not equation A.
B. They are the only values that make both equations true.
C. They show that the equations represent the same line.
D. They satisfy equation A but not equation B.
