What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!

1 answer:

3 0

      24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses: 24 + 3x = 3x + 3(6)

      24 + 3x = 3x + 18

Subtract 3x from each side:    <em>24 = 18</em>

Look at that for a second. Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."

Evaluate 1/3 m- 1- 1/2 n when m=21 and n=12

liq [111]

Answer:

Step-by-step explanation:

First we have to identify 1/3 m. We know that m is 21 and 1/3 of 21 is 7.

Then we find 1/2 on n which we know is 12 so 1/2 of 12 is 6.

Then we subtract. 7-1 is 6 and 6-6 is 0

Hope this helped!!! :D

The time t required to drive a certain distance varies inversely with the speed r. If it takes 12 hours to drive the distance at

aleksklad [387]

Answer:

8.47 Hours

Step-by-step explanation:

The total distance covered in 12 hours with a speed of 60 mph

Distance = 12 x 60 = 720 miles

Now we are required to find the time taken if the same distance is travelled with a speed of 85 mph

Time = 8.47 hours

Given the following system of equations: -4x+8=16, 2x+4y=32 what action was completed to create this new equivalent system of eq

castortr0y [4]

The equation (1) is divided by 2 to create new equivalent system of equations.

Step-by-step explanation:

The given systems of equations are:

$-4x+8y=16\,\,\,(1)\\2x+4y=32\,\,\,(2)$

Considering 8y instead of 8 in eq(1)

We need to identify what action was completed to create this new equivalent system of equations? $-2x+4y=8, 2x+4y=32$

Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e

$-4x+8y=16\\Divide\,\,by\,\,2:\\-2x+4y=8$

While second equation is same as given.

So, The equation (1) is divided by 2 to create new equivalent system of equations.
