what is: 2x/7 - 18 = 6

### Answers

**Answer:**

x = 84

**Step-by-step explanation:**

[tex] \frac{2x}{7} - 18 = 6[/tex]

Add 18 to both sides of the equation

That's

[tex] \frac{2x}{7} + 18 - 18 = 6 + 18 \\ \frac{2x}{7} = 24[/tex]

Multiply through by 7 to eliminate the fraction

[tex]7 \times \frac{2x}{7} = 24 \times 7 \\ 2x = 168[/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{168}{2} \\ [/tex]

We have the final answer as

x = 84

Hope this helps you

Given:

[tex] \frac{2x}{7} - 18 = 6[/tex]

To Find:

The value of x.

Solution:

By adding 18 to both the sides, we get

[tex] \frac{2x}{7} = 24[/tex]

By taking 7 to the RHS, we get

[tex]2x = 24 \times 7 = 168[/tex]

By taking 2 to the other side, we get

[tex]x = \frac{168}{2} = 84[/tex]

Answer:

The value of x is 84.

Graph: 3x-5y=15 an actual graph

### Answers

**Answer:**

*See the attachment*

**Step-by-step explanation:**

Hi there !

**x = 0**

*3(0) - 5y = 15*

*- 5y = 15 | (-)*

*5y = - 15*

*y = - 15 : 5*

*y = - 3*

y intercept (0 ; - 3)

2. **y = 0**

*3x - 5(0) = 15*

*3x = 15*

*x = 15 : 3*

*x = 5*

x intercept ( 5 ; 0)

*Good luck !*

What is the slope of the graph below?

### Answers

**Answer:**

It is negative 1.

-1/1

Give me brainliest please!!

The slope of this graph is -1.

I determined this by using the equation slope= rise/run. In this case, the rise is one and the run is one. This means that the slope is one. Additionally, I notice that the slope is a negative slope which is how I got -1.

You can also use the equation slope = (y2 - y1) all over (x2 - x1). You can do this by getting to ordered pairs from the graph. I took (0,3) and (3,0). So, My equation would be 3-0 all over 0-3. This comes out to 1/-1, which proves the slope is -1.

So again, your answer is the slope is -1.

Hope this helps :)

A recipe for homemade modeling clay includes 13 1 3 cup of salt for every cup of water. If there are 6 cups of salt, how many gallons of water are needed?

### Answers

Answer:

9/320 gallons of water or 0.028125 gallons of water

Step-by-step explanation:

We are told in the question:

13 1/3 cup of salt = 1 cup of water.

6 cups of salt =

Cross Multiply

= 6 × 1/ 13 1/3

= 6 / 13 1/3

= 6 ÷ 40/3

= 6 × 3/40

= 18/40 cup of water.

= 9/20 cup of water.

16 cups of water = 1 gallon

9/20 cup of water =

= 9/20 × 1/16

= 9/20/ 16

= 9/20 ÷ 16

= 9/20 × 1/16

= 9/320 gallons of water or 0.028125 gallons of water

Therefore, 9/320 gallons of water or 0.028125 gallons of water is needed for 6 cups of salt
