Answer:

(2x+12)

Step-by-step explanation:

We can re-write (2x+8)+4 using the associative property of addition. The associative property states that you can move around the parenthesis in an addition problem.

We can write (2x+8)+4 as 2x+(8+4).

2x+(8+4) = 2x+12.

Answer:

2x + 12

Step-by-step explanation:

Example of Associative Property Addition:

a + (b+c) = b + (a+c)

Now, implement it to the given expression:

(2x+8) + 4 = 2x + (8+4)

That simplifies to:

2x + 12

A freight train is carrying goods across the country. The number of gallons of fuel it has used varies directly with the distanc
Maru [420]

Answer:

<u>0.125 miles per gallon.</u>

Step-by-step explanation:

After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

---------------------

Extra

---------------------

<u><em>IF</em></u> it were how many gallons per mile, you would divide both answers by 25 resulting in <u>8 gallons per mile.</u>

Explain how to do this math problem all the way threw 6times2 and 7/10
Anestetic [448]
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10.  That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5

X – 10y = 18<br> -6x – 10y = 32
viva [34]

Answer:

Step-by-step explanation:

x - 10y = 18

-6x - 10y = 32

Since both equations have -10y, we can subtract the second equation from the first to try and solve for x:

(x - 10y) - (-6x - 10y) = 18 - 32

x - 10y + 6x + 10y = -14

7x = -14

x = -2

With this, we can plug the value back into the first equation to solve for y:

(-2) - 10y = 18

-2 - 10y = 18

-10y = 20

y = -2

Therefore, the solution is x = -2, y = -2

There is a 5% tax on a bicycle . if the tax is $43 , what was the original price of the bike
Minchanka [31]
Tax is 5% of the original price. So if i multiply by 20 i can easily find the original 100%.

20 x $43 = $860

You can check if by doing 860 x 0.05 = $43
