The correct answer is D. 1,136
This is because when you divide 3,000 by 140 (the total amount of people surveyed) you get about 21. Then multiply 21 by the number of people who chose N. Monroe (53). That answer is 1,136.
Answer:
The value of x is 2 and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- -7x + y = – 19
- -2x + 3y = – 19
<h3><u>To </u><u>Find</u>;</h3>
<h3><u>B</u>y<u> </u><u>Usin</u>g<u> </u><u>Elimination</u><u> </u><u>Method</u>;</h3>
First name the equation
- -7x + y = – 19 ...(1)
- -2x + 3y = – 19 ...(2)
Now, Multiply equation (1) by 3 we get,
3 × (-7x + y = – 19)
-21x + 3y = – 57
Now, Eliminate
-21x + 3y = – 57
-2x + 3y = – 19
<u>+</u><u> </u><u> </u><u> </u><u> </u><u>–</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+</u><u> </u><u> </u><u> </u><u> </u>
-19x = -38
x = -38/-19
x = 2
Now, Put the value of x in equation (2) we get the value of y.
-7x + y = – 19
-7(2) + y = – 19
-14 + y = -19
-14 + 14 + y = -19 + 14
y = -5
Thus, The value of x is (-5) and the value of y is 2.
<h3>
<u>For </u><u>Verification</u>;</h3>
-7x + y = – 19
-7(2) + (-5) = – 19
-14 – 5 = – 19
-19 = -19
-2x + 3y = – 19
-2(2) + 3(-5) = – 19
-4 – 15 = – 19
-19 = -19
Here, L.H.S = R.H.S
Hence Verified!
