5x + 9 equals 2x + 12. What is the value of x?

Answer: x = 1

Step-by-step explanation: When we have this kind of setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side

by subtracting 2x from both sides of the equation.

That gives us 3x + 9 = 12.

Now we can move our numbers to the right by

subtracting 9 from both sides and we get 3x = 3.

Now divide both sides by 3 and <em>x = 1</em>.

Answer:

2.46×10^8

Step-by-step explanation:

The decimal point is here

246000000.

Then it must be moved up to here

2.46000000

Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8

Then you have

2.46×10^8

KatRina [158]

Answer:

3

Step-by-step explanation:

It is a well known trick that when you add together the digits of a number, if they are a multiple of 3 then the number is divisible by 3. Let's go through the options and check them:

7+5+7+0=19 not a multiple of 3

7+5+7+1=20 not a multiple of 3

7+5+7+2=21 multiple of 3

7+5+7+3=22 not a multiple of 3

7+5+7+4=23 not a multiple of 3

7+5+7+5=24 multiple of 3

7+5+7+6=25 not a multiple of 3

7+5+7+7=26 not a multiple of 3

7+5+7+8=27 multiple of 3

7+5+7+9=28 not a multiple of 3

As you can see, only 3 of these were possibilities that satisified the conditions. Hope this helps!
