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>

7. Find all geometric sequences such that the sum of the first two terms is 24 and the sum of the first
sesenic [268]

Answer:

Step-by-step explanation:

Let the first term is n, then the second term must be an where a is a common ratio, and the third term is a^2 n

so, n + an = 24

n + an + a^2 n = 26

solve for a, then solve for n

joja [24]
5x+100=10x
-5x on both sides (10x-5x=5x)
100=5x
divide by 5 on both sides (100/5= 20)
20=x

The value of y varies directly with x. If x = 3, then y = 22. What is the value of x when y equals 105
Nutka1998 [239]

Answer:

Varies directly uses the formula: y/x = k

22/3 = 7.33

105/x = 7.33

105/x (7.33/x) = 7.33(x/7.33)

105/7.33 = x

x = 14.32
