What is 36 divide by 837
Dominik [7]
You want to take 837 out of 36. 
you can get 837 out of 3 0 times so you tack on the 6(0)
you get 837 out of 36 0 times so you tack on a zero(00)
Because you are adding a 0, you are now creating a decimal
you get 837 out of 360 0 times so you tack on a 0 (00.0)
You get 837 out of 3600 4 times so you put the 4 after the 0s (00.04)
Now you multiply 4 and 837 to get 3,348 and take that away from 3600 to get 252
Not you tack on a 0. 
You get 837 out of 2520 3 times so you tack the 3 on behind the 4. (0.043) 
Because of significant digits, your answer is 0.043

Create an equation with a solution closest to 0 using digits 1 to 9
steposvetlana [31]

Complete Questions:

<em>Create an equation with a solution closest to 0 using digits 1 to 9 </em>

<em>_x + _ = _x + _</em>

<em></em>

Answer:

See Explanation

Step-by-step explanation:

Given

_x + _ = _x + _

Required

Fill in the gap using 1 to 9 to give a result close to 0

First, you have to determine what kind of numbers that are close to 0;

In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;

Next, is to fill in the gaps using trial by error method

5x + 2 = 2x + 3

Checking the above expression

<em>Collect Like Terms</em>

<em></em>5x - 2x = 3 - 2<em></em>

3x = 1

Divide equation by 2

x = 0.33 <em>(Approximated)</em>

Another trial is

6x + 8 = 2x + 7

Checking the above expression

<em>Collect Like Terms</em>

<em></em>6x - 2x = 7 - 8<em></em>

4x = -1

Divide equation by 4

x = -0.25 <em>(Approximated)</em>

<em>I'll stop here but note that, there are more expressions that can fill in the gaps</em>
