Answer:

D

Step-by-step explanation:

9x+(5y+x)-3y

Remove the parenthesis

When there is a "+" in front of an expression in parentheses, the expression remains the same

9x+5y+x-3y

Collect like terms

(9x+x)+(5y-3y)

10x+2y

Answer:

C and D

Step-by-step explanation:

Let's add this all together.

9x + 5y + x - 3y

Combine like terms 5y + -3y and 9x + x

10x + 2y

So we know D is at least correct.

What else? C is also correct, because we can expand it outward.

10x + 5y - 3y = 10x + 2y

A and B are not correct! We can't multiply the ys or the xs.

Systems of Linear Equations What are the different ways to solve a system of linear equations? When do you get an answer to a sy
Mrac [35]

Answer:

Different ways to solve a system of linear equations:

  • isolate one variable in one equation and replace it in the other equation
  • multiply/divide one equation by a constant and then add/subtract it to the other one, so that only one variable remains
  • graph the equation and look at the intersection point

If you graph the system:

  • there is only one solution if the lines intersects at only one point
  • there is no solution if the lines don't intersect each other (they are parallel)
  • there are infinitely many solutions if the lines overlap each other (they are the same equation multiplied by some constant)

Step-by-step explanation:

1st system

y = -x – 7  

y = 4/3 x – 7  

solution: x= 0, y = 7

2nd system

y = -3x – 5  

y = x + 3  

solution: x = -2, y = 1

3rd system

y = -2x + 5  

y = 1/3 x – 2

solution:  x = 3, y = -1

4th system

3x + 2y = 2  

x + 2y = -2  

solution: x = 2, y = -2

5th system

x + 3y = -9  

2x – y = -4

solution:  x = -3, y = -2

6th system

x – 2y = 2

-x + 4y = -8

solution:  x = -4, y = -3

7th system

5x + y = -2  

x + y = 2

solution: x = -1, y = -3

Determine wether the ratios are proportional: 6/36 and 1/6
dangina [55]
They are proportional. If you divide 6/36 by 6 on the numerator and the denominator, you get the same fraction of 1.6.

Gema has 4 <br> FT of wire how much wire does she need to wrap one meter of her garden?
Dmitry [639]

Answer:

3.28 feet

Step-by-step explanation:

One meter equals to 3.28 feet.

The question isn't exactly clear what Gema wants to use her wire for, because "wrap one meter" isn't correct.

You wrap something around something else...  and you can't wrap something around a meter.  You can wrap around a square meter by doing the perimeter... but then you'd need more than meter to do the perimeter of a square meter (the perimeter can be around 4 meters).

So, assuming she has a length of 1 meter to cover, she would need 3.28 feet.

Zahara constructs 5 mirror frames in 30 minutes. At that rate, how many mirror frames can Zahara make in 9 hours
lord [1]

Answer:

90

Step-by-step explanation:

I believe it is 90 because when you take 30 minutes plus 30 minutes that makes 1 hour, and when you take 5 plus 5 equals 10. So, that means 10 every hour. So 10 times 9 is 90. Which gives you the answer of 90 mirror frames.
