Answer:
500 people
Step-by-step explanation:
Let the total number of people took the survey = x
Since 12 out of every 15 people prefer eating at a restaurant.
Therefore, fraction of total person surveyed who preferred eating at restaurant = people
If the number of people selected eating at restaurant = 400
Hence, = 400
x =
x =
x = 500
Total 500 people took the survey.
12 = 400
=
15 = 15 *
= 500.
∴ 500 people took the survey
2y − x = 6
Which statement is true about the coordinates of the point that is the solution to the system of equations?
A. It is (−2, 2) and lies on both lines.
B. It is (−5, 3) and lies on both lines.
C. It is (−5, 3) and does not lie on either line.
D. It is (−2, 2) and does not lie on either line.
3y+x=4
2y-x=6
Solve x+3y=4 for x
Add -3y to both sides
x+3y-3y=4-3y
x=-3y+4
Substitute -3y+4 for x in -x+2y=6
-x+2y=6
-(-3y+4)+2y=6
Simplify both sides of the equation
5y-4=6
Add 4 to both sides
5y-4+4=6+4
5y=10
Divide both sides by 5
5y/5=10/5
y=2
Substitute 2 for y in x=-3y+4
x=-3y+4
x=(-3)(2)+4
x= -6+4
x= -2
Answer : x=-2 and y=2
The answer is A
it is (-2,2) and lies on both lines
I hope that's help !
