Answer: To clear an equation of decimals, multiply each term on both sides by the power of ten that will make all the decimals whole numbers. In our example above, if we multiply .25 by 100, we will get 25, a whole number. Since each decimal only goes to the hundredths place, 100 will work for all three terms.
So let's multiply each term by 100 to clear the decimals:
(100)0.25x + (100)0.35 = (100)(-0.29)
25x + 35 = -29
Now we can solve the equation as normal:
25x + 35 - 35 = -29 - 35
25x = -64
x = -2.56 Since the original was in decimal form, the answer should most likely also be in decimal form.
Let's look at one more:
1.75x + 4 = 6.2
We have to think a little more carefully about what multiple of ten to use here. 6.2 only needs to be multiplied by 10, but 1.25 needs 100, so we will multiply every term by 100. Don't forget to multiply the 4 by 100 as well.
(100)(1.75x) + (100)(4) = (100)(6.2)
175x + 400 = 620
We had to be extra careful as we multiplied by 100. Now we can solve the equation as normal:
175x + 400 - 400 = 620 - 400
175x = 220
x = 1.26

Answer:
Step-by-step explanation:
4x - 2y = 6
-2y = -4x + 6
y = -4x/-2 + 6/-2
y = 2x - 3
There is not really a rule to figuring out this question.There are kinda multiple ways to determine the volume of a 3D object. It really depends on what 3D object you are trying to find the volume for. But i can give you and example. Say you have a 3 dementional cube and you need to find the volume of that cube. You would take the bottom square of the cube and fine the area like you would any other square. But since this is a cube you have height to worrie about. So you will take the area you got for the bottom square and times that by the height. You will then have your answer. And if you are dealing with a cylinder same thing goes except with circle. Find the area of the bottom circle then times that by the area. Hope this helped sorry for taking so long.
