What Value Of X Makes This Equation True? 2x + 3 = 9
Answer 2

Answer:

[tex]\boxed {\tt x=3}[/tex]

Step-by-step explanation:

We want to solve for x, therefore we must isolate the variable.

We are given the equation:

[tex]2x+3=9[/tex]

3 is being added to 2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.

[tex]2x+3-3=9-3[/tex]

[tex]2x=9-3[/tex]

[tex]2x=6[/tex]

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

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

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

[tex]x=3[/tex]

Let's check our solution. Plug 3 in for x and solve.

[tex]2x+3=9[/tex]

[tex]2(3)+3=9[/tex]

[tex]6+3=9[/tex]

[tex]9=9[/tex]

This checks out, so we know our solution is correct.

The solution to the equation 2x+3=9 is x=3

A van can travel 18 miles on each gallon of gasoline. At that rate, how many miles can the van travel on 15 gallons of gasoline? 33 miles 83 miles 120 miles 270 miles Mark this and return

Answers

Answer:

270 miles

Step-by-step explanation:

if 1 gallon = 18 miles

then 15 gallons = x miles

cross multiply

1 × x = 15×18miles

x = 270 miles

so it travels 270 miles on 15 gallons of gasoline

Write 6 x 10 x 10 x 10 x 10 with an exponent. ​

Answers

Answer:

the answers is 6x 10 4

Step-by-step explanation:

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

What are exponents?

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

We have been given an expression as

6 x 10 x 10 x 10 x 10

Here we can see the base 10 multiplied by itself 4 times.

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

D)

Answers

Answer:

D

Step-by-step explanation:

Given

[tex]\frac{1}{4}[/tex] (2x + 8) = - 16

Multiply both sides by 4 to clear the fraction

2x + 8 = - 64 ( subtract 8 from both sides )

2x = - 72 ( divide both sides by 2 )

x = - 36

Answer:

The answer is option D

Step-by-step explanation:

[tex] \frac{1}{4} (2x + 8) = - 16[/tex]

First multiply through by 4

That's

[tex]4 \times \frac{1}{4}(2x + 8) = - 16 \times 4 \\ 2x + 8 = - 64[/tex]

Subtract 8 from both sides

We have

[tex]2x + 8 - 8 = - 64 - 8 \\ 2x = - 72[/tex]

Divide both sides by 2

That's

[tex] \frac{2x}{2} = - \frac{72}{2} [/tex]

We have the final answer as

x = - 36

[tex]\bf Step-by-step~explanation:[/tex]

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

[tex]\bf Step~1:[/tex]

Divide the number of candy bars (34), by the number each box can hold (5)

[tex]\bf\frac{34}{5}=6.8[/tex]

Since we cannot have 6.8 boxes, we have to round down to 6.

[tex]\boxed{\bf Our~final~answer:~6~boxes}[/tex]

[tex]\bf Check~our~answer:[/tex]

To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!

Grissom draws different sized spheres in a notebook. He knows there is a relationship between the volume of the sphere and the length of its diameter. What is the independent quantity in the situation?

Answers

Answer:

The independent quantity in the situation is the length of the diameter.

Step-by-step explanation:

Consider a relationship between two variables.

Of the two variables one variable is dependent upon the other.

Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variable values are changed.

Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.

In this case, it is provided that Grissom knows there is a relationship between the volume of the sphere and the length of its diameter.

With every sphere that Grissom draws, the volume of the sphere changes according to its diameter length.

That is the volume of the sphere depends upon the length of its diameter.

Thus, the independent quantity in the situation is the length of the diameter.

The stock of Company A gained 6.5% today to $40.47. What was the opening price of the stock in the beginning of the day?

Answers

Answer:

$37.84

Explanation:

We need to see what to multiply $40.47 by to find the price of the stock from the beginning. First, we need to subtract 100% by the percentage of gain.

100% - 6.5% = 93.5%

Next, we need to divide 93.5% by 100.

93.5% ÷ 100 = 0.935

Lastly, we multiply $40.47 by 0.935 and round it to the nearest hundredth.

40.47 × 0.935 = 37.83945 --> 37.84

Hope this helped!

Owen knows he only has three pencils in his backpack, and they are all yellow. He reaches into his backpack without looking and takes out a pencil. What is the probability that the pencil was yellow? Answer options with 5 options A. 0-thirds B. 1-third C. 2-thirds D. 3-thirds E. 3 over 1 I NEED ACTUAL ANSWERS NOT JUST STUPID PEOPLE WITH A POOR SENSE OF HUMOR

Answers

Answer:

D; 3-thirds

Step-by-step explanation:

Here is a probability question.

Firstly, we need to understand that the probability of any event is between 0 and 1; it cannot be negative and cannot be more than 1.

So the probability we want to calculate here is simply the probability of drawing a yellow pencil.

The way to go about this is by dividing the number of yellow pencils by the total number of pencils

Mathematically;

Probability of bringing out a yellow pencil= Number of yellow Pencils/ Total number of pencils

From the question, we are told that the number of pencils = number of yellow pencils = 3

Thus the probability will be 3/3 = 1

This cannot be found in the options right?

1 is the same as 3-thirds meaning 3 * 1/3 = 1

Answers

The {x} coordinate of the solution to the following system of equations is - 1.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the system of equations as -

x − y = − 3

x + 3y = 5

We can write -

x - y = - 3

y = x + 3

So, we can write -

x + 3(x + 3) = 5

x + 3x + 9 = 5

4x = - 4

x = - 1

Therefore, the {x} coordinate of the solution to the following system of equations is - 1.

the prism has a volume up to 150.find the length of the prism

Answers

Step-by-step explanation:

We have to know that in order to solve for the volume of a rectangular prism, we have to use this formula: l * w * h. This stands for length multiplied by width multiplied by height.

Step 1

Let's look at the numbers we already have. The height of the prism is 4 feet and the width is 5 feet. When we multiply them together, we got 20 feet.

Step 2

The volume of this prism adds up to 150 square feet. To find the length of this prism, we have to divide 150 by 20.

[tex]150 / 20=7.5[/tex]

Our final answer: l = 7.5 feet

We can check our answer by multiplying all the numbers together.

4 * 5* 7.5 = 150

The cross-sectional areas of a right pyramid and a right cylinder are congruent. The pyramid has a height of five units, and a right triangle has a height of three units. Which conclusion could be made from the given information

Answers

Answer:

the volume of the right cylinder is 1.8 times the volume of the pyramid

Step-by-step explanation:

The volume of a pyramid is

[tex]V = \dfrac{1}{3} \times B\times H[/tex]

where the height of the pyramid is 5

[tex]V = \dfrac{1}{3} \times B\times 5[/tex]

[tex]V = \dfrac{5}{3} B \ units ^3[/tex]

On the other hand, the volume of a right cylinder is

V = BH

where the height of the right cylinder = 3 units

V = 3 B units³

Since we know that the cross-sectional areas are congruent, comparing the two-volume, we have the ratio of their volumes to be:

[tex]\dfrac{V_p}{V_c}= \dfrac{\dfrac{5}{3}B}{3B}[/tex]

[tex]\dfrac{V_p}{V_c}= \dfrac{5}{9}[/tex]

[tex]9 V_p = 5 V_c[/tex]

[tex]V_c = 1.8 \ V_p[/tex]

Hence, the volume of the right cylinder is 1.8 times the volume of the pyramid
