The correct answer is D

Answer:

D) multiply second equation by -6, solution (0,-2)

Step-by-step explanation:

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.

As such, in the given set of equations

12x – 3y = 6

2x – y = 2

We may make the coefficients of x the same by multiplying the second by 6 or the coefficient of y by multiplying the second by 3. Using the first

12x – 3y = 6

12x – 6y = 12

equation 1 - equation 2

3y = -6

y =  -2

2x + 2 = 2

x = 0

If a town starts with population of 63,500 that declines by 700 people each year, construct an equation to model its population
ankoles [38]

The equation would be 63500-700x=P, where 63500 is the original population, -700 is the amount the population decreases each year, x is the number of years, and P is the total population.


To answer the second part of the question, plug in 53000 for P and solve for x:

63500-700x=53000

<em>*Subtract 63500 from both sides*</em>

-700x=-10500

<em>*Divide both sides by -700*</em>

x=15


It would take 15 years for the population to drop to 53000.


Hope this helps!!

Find the unknown. = (65 × 3) + 9
alekssr [168]

Answer:

204

Step-by-step explanation:

Following the order of operations, what is within the parenthesis is solved first.

<em>65 x 3 = 195</em>

Then, you add 9 to 195.

<em>195 + 9 = 204</em>

<em>204</em> is the final answer.

Have a nice day! ^-^
