If you have no calculator, pretend like the decimals aren’t there then add them back depending on how many places you have after the decimal. for example: 2.5 times 2.5, if you pretend there are no decimals, you get 625, then you have to add the decimals back. since you have 1 digit after each decimal in each number, you add 1+1=2 to get the number of places you have to add back. so you get 6.25

Answer:

You can use multiplication normally. But then you must add the decimals

Step-by-step explanation:

Lets do 24.56 x 32.78

It would equal 8050768 without decimal points

But now we must add the decimal points in, count the amount of numbers that appear after the decimal, which is 4

So 8050768 = 805.0768

12. Solve the equation 6 - 6x = 5x – 9x - 2.
ycow [4]

Answer:

x=4

Step-by-step explanation:

6 - 6x = 5x – 9x - 2

6+2=5x-9x+6x

8=2x

4=x

What you need to do to be able to solve this is move all of the terms that have no variable and the ones that have the same variable to the other side. Once you have that, you should be able to do 6+2 and solve the side that has variables as if it has no variables. Remember that you have to flip the sign when you are moving all of the numbers. Then when you get to the step where both sides have only one number, that is when you would divide the other number, which in this case is 8, by 2, which is the number correlated with x. And that should get x by itself, and give you the solution.

The first bottle has 4 pints or 8 cups or 2 quarts.  The seconds has 1.25 quarts or 5 cups or 2 1/2 pints.  The one with 4 pints would have more so it would be a better deal.

Rememeber thath you can do anything to an eqation as long as you do it to both sides

12a-7+12a=13
add like terms
24a-7=13
add 7 to both sides
24a=20
divide both sides by 24
a=20/24
