Geometry- Solve the portion. Question#4<br>​
kotykmax [81]

Answer:

d=18

Step-by-step explanation:

<h3>First let's write our equation</h3><h3 /><h3>\frac{6}{d-6} =\frac{4}{8}</h3><h3 /><h3>Reduce</h3>

<em>Definition -  </em><em>reduction refers to the rewriting of an expression into a simpler form</em>

<h3 />

We can reduce \frac{4}{8} to \frac{1}{2}

Our equation is now \frac{6}{d-6} =\frac{1}{2}

Now we can cross multiply

<em>Definition - </em><em>given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.</em>

d-6=12

<h3>Add</h3>

We are adding because we want our variable to be on one side of the equation

d=18

<h3>To check we can show our equation but instead of d we have 18</h3><h3 />

\frac{6}{18-6} =\frac{1}{2}

Subtract and we get

\frac{6}{12} =\frac{1}{2}

Which makes it true

<h3><em>Have a good day!</em></h3>

PLZ HELP ASAP WILL MARK BRAINIEST

1. The 2nd number line represents the inequality.

Explanation:

In words, the inequality reads "negative six is less than x, which is less than or equal to two". On the number line, the open circle at negative six means that -6 is not a solution to the inequality: -6 < x. The point at positive two means that positive two is a solution to the inequality: x ≤ 2. Therefore, all numbers greater than -6 and less than or equal to +2 are solutions to the inequality. This is shown on the second number line.

2. False

Explanation:

In words, the inequality reads "x is less than negative five". This means that all numbers less than -5 are solutions to the inequality. Positive four is not less than negative five, so it is not a solution to the inequality.

3. x > 2

Explanation:

To solve the inequality, we have to move all the terms that do not contain x to one side. This inequality is simple because it only requires one step: subtraction.

Solve for x: x + 3 > 5

1. Subtract 3 from both sides to get x by itself:

x + 3 - 3 > 5 - 3

2. Simplify

x > 2
