Answer:

Step-by-step explanation:

Combine like terms.  2x and 4x are like terms, and their sum is 6x.

-6 and -12 are like terms also; their sum is -18.

Thus, the sum of (2x-6)+(4x-12)

in simplest terms is  6x - 18.

How to convert 264 yds/1 s to mi/day?
dusya [7]

Answer:

12,960\ \frac{miles}{day}

Step-by-step explanation:

we know that

1\ mile=1,760\ yards

To convert yards to miles multiply by 1/1,760

1\ hour=3,600\ seconds

1\ day=24\ hours

so

(24)3,600=86,400

1\ day=86,400\ seconds

To convert seconds to day multiply by 1/86,400

In this problem we have

264\ \frac{yd}{sec} =264\ \frac{(1/1,760)}{(1/86,400)}=264\ (\frac{86,400}{1,760})=12,960\ \frac{miles}{day}

Helps with this math problem please
olasank [31]
First we are going to express both equation in terms of  y to compare their slopes:
For our first equation:
-x=1-y
-x-1=-y
y=x+1
For our second equation:
-1+y=x+2
y=x+3
So now we have our system of equations in terms of y:
\left \{ {{y=x+1} \atop {y=x+3}} \right.
Notice that the slope, the coefficient of x, in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.

We can conclude that we can classify the system of equations as parallel.
