what is the solution for x in 12x-4=5x+24

### Answers

**Answer:**

x = 4

**Step-by-step explanation:**

12x - 4 = 5x + 24

First subtract 5x from both sides

That's

12x - 5x - 4 = 5x - 5x + 24

7x - 4 = 24

Add 4 to both sides

That's

7x - 4 + 4 = 24 + 4

7x = 28

Divide both sides by 7

We have the final answer as

x = 4

Hope this helps you

**Answer:4**

**Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.**

Point G is on line segment FH. Given FH = 19 and FG = 12,

determine the length GH.

### Answers

**Answer:**

7

**Step-by-step explanation:**

Let’s think about this like a number line.

If we have a number line with the ends of F and H, and G is somewhere in between, it would look something like this.

F———-G———H

We know that FH = 19 and that FG is 12.

This means that GH will be the FH - FG

[tex]19 - 12 = 7[/tex]

So FG is 7.

There are liquids of different densities together in a container. What will happen to the liquid with the lowest density? It will move to the bottom. It will move to the top. It will bubble out as a gas. It will form a solid.

### Answers

**Answer:**

It will move to the top.

**Step-by-step explanation:**

The **liquid** with the **lowest density** will move to the **top**. Therefore, **option B** is the **correct answer**.

Given that, there are liquids of different densities together in a container.

We need to determine what will happen to the liquid with the lowest density.

What is density?

The **density**, of a **substance**, is its **mass per unit volume**.

The **density** of a **liquid** determines whether it will float on or sink in another liquid. A **liquid** will **float** if it is **less dense** than the liquid it is placed in. A **liquid** will **sink** if it is **denser** than the liquid it is placed in.

Now, the **liquid** with the** lowest density** will move to the **top**.

Therefore, **option B** is the **correct answer**.

The **rate **of **change **is 1/4 **shovels**/ minute of 0.25 **shovels**/ minute.

What is rate of change?

**Rate **of **change **is the increase or decrease of any **property **with respect to any other **property**, when rate of change is studied for a time duration, the ratio of the difference in the **property **from initial state to its value at the end of the **time duration **is divided by the total time.

For an **expression**, the rate of change is determined by **differentiation**.

The hardware store sold 15 **shovels **in sixty minutes.

The **number **of shovels sold is 15.

The **time duration **in which the shovels are sold is 60 minutes.

The **rate **of the shovels sold every **minute **has to be determined.

**Rate **= ( No. of shovels sold) / Time duration

**Substituting **the values

**Rate **= 15 /60

**Rate **= 1/4

difference of two numbers is 166. The sum of the same two numbers is 234. What are the two numbers?

### Answers

**Answer:**

The numbers are 100 and 234

**Step-by-step explanation:**

Let the numbers be x and y

The statement

difference of two numbers is 166 is written as

x - y = 166.......... Equation 1

The sum of the same two numbers is 234 is written as

x + y = 234 ............. Equation 2

Solve the equations simultaneously

Add both equations 1 and 2

That's

x + x + y - y = 166 + 234

2x = 400

Divide both sides by 2

x = 100

Substitute the value into the first equation

That's

100 + y = 234

y = 100 - 234

y = 134

The numbers are 100 and 234

Hope this helps you

The answers are X= 100 and Y= 134
