Solve

6x + 5 = 3x + 14

Answers

Answer:

x = 3

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

6x + 5 − 3x = 3x + 14 − 3x

3x + 5 = 14

Step 2: Subtract 5 from both sides.

3x + 5 − 5 = 14 − 5

3x = 9

Step 3: Divide both sides by 3.

[tex]\frac{3x}{3} = \frac{9}{3}[/tex]

x = 3

Hope it helps!!

The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

6x + 5 = 3x + 14

Simplify the equation, then we have

6x + 5 = 3x + 14

6x - 3x = 14 - 5

3x = 9

x = 3

The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.

The volume of a rectangular prism is the product of its length, width, and height. The length of a rectangle prism is 3 feet more than five times its height. The width is 5 feet less than six times its height. Express the length and width in terms of the height h. The length is The width is (Be sure to Write down the expanded form of the expression for the volume: expand the volume expression) (Express the interval in which the In what range must the height fall? He height must be)

Answers

The length and width in terms of the height h is  5h+3 feet and 6h-5 feet respectively, the volume will be  [tex]30h^3 - 7h^2 -15h[/tex] units and the height must be in the interval of [tex][0,\infty)[/tex].

According to the question,

The height of the rectangular prism is h.

The length of the rectangular prism  is  5h+3 feet

The width of the rectangular prism  is  6h-5 feet

The volume of the rectangular prism can be calculated as:

[tex]Length \times width \times height = Volume[/tex]

Substitute the value of height, length  and width in the formula:

[tex]V = (5h+3) \times (6h-5) \times h[/tex]

V = [tex](30 h^2 -7h-15)h[/tex]

[tex]V = 30h^3 - 7h^2 -15h[/tex]

The height is always positive. So, the interval in which the In what range must the height fall is [tex][0,\infty)[/tex].

The length and width in terms of the height h is  5h+3 feet and 6h-5 feet respectively and the volume will be  [tex]30h^3 - 7h^2 -15h[/tex] units

2/9x + 3 > 4 5/9
what graph shows the values that satisfy the expression

Answers

Answer:

Step-by-step explanation:

In graphing inequalities, the first thing to do is graph the equation first irregardless of the inequality symbol. In the given problem, the equation to be graphed is f(x) = 2/9x + 3. Since it has a general form of y=mx + b, this is a linear function. Plot the graph by assigning arbitrary points of x, then you get the corresponding f(x) values. Graph the x values against the f(x) values. The blue line the attached picture will be formed.

Next, you solve the equation by finding x. Just don't mind the inequality symbol:

2/9 x + 3 > 4 5/9

2/9x > 4 5/9 - 3

2/9x > 14/9

x > 14/9 ÷ 2/9

x > 7

Hence, the value of x must be greater than 7. To show this in the graph, find the line where x=7. Create a partition using that line, then shade the rest of the portion where x is greater than 7 until infinity.

A train goes at a constant speed. If it covers 150 miles in 2 1 2 hours,

What distance would it cover in 7 hours?

Answers

Answer: I think is 420 miles in 7 hours

hope this helps :D

Step-by-step explanation:

Answer:

A train would cover 180 miles in 3 hours, So in 6 hours it will cover 360 miles, in 7 hours it will cover 420 miles.

Step-by-step explanation:

150 miles → 2 1/2 hours = 150 minutes

x miles     → 3 hours = 180 minutes

(150 × 180) ÷ 150 = x miles

27,000 ÷ 150 = x miles

180 = x miles

find the length of the angle inducated for each trapezoid.​

Answers

First things first: all quadrilateral have an interior of 360⁰. With that info, you can do your exercice.

the first one:

the angle P =90⁰

the angle Q=90⁰

So you do the deduction:

360⁰-90⁰-90⁰-65⁰= 115⁰

the second one:

the angle F=60⁰

so you do the same thing as number one:

360⁰-60⁰-60⁰= 240⁰

240⁰/2= 120⁰
