Answer: Yes it does matter because you can't add the like terms if they aren't the same.
Step-by-step explanation: 2x+8y you can't add these two because they don't have the same like terms.

4. The x-coordinate of the solution is 9.</span><span>
5. The y-coordinate of the solution is −8 .</span><span>
6.The ordered pair that is the solution to the system lies in Quadrant IV .</span><span>
Proof:
Solve the following system:
{4 x + 3 y = 12 | (equation 1)
{2 x + 3 y = -6 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 3 y = 12 | (equation 1)
{0 x+(3 y)/2 = -12 | (equation 2)
Multiply equation 2 by 2/3:
{4 x + 3 y = 12 | (equation 1)
{0 x+y = -8 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = 36 | (equation 1)
{0 x+y = -8 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 9 | (equation 1)
{0 x+y = -8 | (equation 2)
Collect results:
Answer: {x = 9 , y = -8</span>
Answer:
An angle that measures exactly 180° is known as a <u>straight</u> angle
Step-by-step explanation:
A straight angle is basically just a line. It is equal to two right angles (which are 90 degrees) and it is also half of a circle.
I hope this was helpful! If you need any more information on straight angles or any other angles, let me know! Have a lovely day! :)
Answer:
30 yards per minute.
Step-by-step explanation:
Unit rate is basically when the denominator is 1. In this case, 450 is divisible by 15, so if you divide that, you get 30.
