What is the first step in determining if 6 is a solution to 3x-18?

Answer:

[tex]10 + (\frac{2}{3}) a = 50[/tex] is the CORRECT equation.

Step-by-step explanation:

The given question is INCOMPLETE.

Javier asks his mother how old a tree in their yard is. His mother says, “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.” Javier writes the equation { 10 + 2/3} where a is the tree’s age in years. His equation is not correct. What error did he make?

Now here:

a:  The tree’s age in years.

Also,  “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.”

⇒ 10 +  two-thirds of that tree’s age  = 50

[tex]\implies 10 + (\frac{2}{3}) a = 50[/tex]

But in the equation written by Javier, the the third fraction is NOT MULTIPLIED by the age of the tree a in Years.

So, the written equation by Javier is Incorrect.

Now, solving the written correct equation for the value of a, we get:

[tex]\implies 10 + (\frac{2}{3}) a = 50\\\implies (\frac{2}{3}) a = 40\\\implies a = 40 \times (\frac{3}{2}) = 60\\\implies a = 60[/tex]

Hence the correct  age of the tree = 60 years

The student's algebra problem is solved by gathering like terms, simplifying the equation, and then isolating 'w'. The solution to the equation is 'w = 9'.

The subject of this question is mathematics, specifically, the topic is algebra. The equation given is -4+w+17-2/3w=16. We need to solve this equation for 'w'.

To start, we should gather like terms. Therefore, -4 + 17 becomes 13, making our equation 13 + w - 2/3w = 16. We can also rearrange this to w - 2/3w instead, which results in 1/3w = 16 - 13, therefore, 1/3w = 3. To solve for w, we can multiply the both sides of the equation by 3, which leads to w = 3 * 3 or w = 9.

Step-by-step explanation:

16/4=4 (to brother) 16-4=12 (whats remaining) 12/2=6 (to sister)

Ruby gives her sister 6 animals.

To find out how many animals Ruby gives her sister, we need to follow the instructions step by step. Ruby starts with 16 stuffed animals. She gives 1/4 of her collection to her brother, which is equal to 16 * 1/4 = 4. Now Ruby has 16 - 4 = 12 stuffed animals left. Then she gives half of the remaining animals to her sister, which is equal to 12 * 1/2 = 6. So Ruby gives her sister 6 animals.

Answer:

7. [tex]\frac{1}{2}+\frac{1}{3}>\frac{1}{5}[/tex]

8. [tex]0.1+0.15>0.2[/tex]

Step-by-step explanation:

Given:

Three sides of the triangles are given.

For Question 7

1/2 _ 1/3 _1/5

For Question 8

0.1 _ 0.15 _ 0.2

We need to use >, <, and + signs to write inequalities for the relationships among  the sides of the triangles.

Solution:

Part 7.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is [tex]\frac{1}{2}, \frac{1}{3}\ and\ \frac{1}{5}[/tex]

[tex]\frac{1}{2}+\frac{1}{3}>\frac{1}{5}[/tex]

[tex]\frac{5}{6}>\frac{1}{5}[/tex]

So, its satisfy the triangle rule.

Therefore, Inequality is [tex]\frac{1}{2}+\frac{1}{3}>\frac{1}{5}[/tex]

Part 8.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is [tex]0.1, 0.15\ and\ 0.2[/tex]

[tex]0.1+0.15>0.2[/tex]

[tex]0.25>0.2[/tex]

So, its satisfy the triangle rule.

Therefore, Inequality is [tex]0.1+0.15>0.2[/tex]

Use inequalities to compare sides of triangles with >, <, and + signs.

For 7:

1/2 > 1/3

1/3 > 1/5

1/2 + 1/3 > 1/3 + 1/5

For 8:

0.1 < 0.15

0.15 < 0.2

0.1 + 0.15 < 0.15 + 0.2

The height of a parallelogram can be found by solving the equation 'Area = base × height' given the area is 175 square centimeters and the height is 18 centimeters less than the base. The base 'b' and the height 'b - 18' form a quadratic equation that can be solved to find 'b', after which subtracting 18 will give the height.

The question is asking to find the height of a parallelogram given its area and a relationship between the base and the height. The area of a parallelogram is found using the formula Area = base × height. According to the given information, we know that the area is 175 square centimeters. The relationship between the base and the height of the parallelogram is such that the height is 18 centimeters less than the base. Therefore, we can denote the base as 'b' and the height as 'b - 18'. Plugging these into the formula for the area we get 175 = b × (b - 18).

To solve for 'b', we can set up and solve a quadratic equation. After finding the value of 'b', we can calculate the height by subtracting 18 centimeters from our value for 'b'. Let's go through the steps:

After solving the quadratic equation, we would get the value of 'b' and accordingly the value of 'b - 18' which is the height of the parallelogram in centimeters.

C = 44 is the circumference

in general, the circumference of a circle is

C = 2*pi*r

Plug in C = 44 and solve for r.

C = 2*pi*r

44 = 2*pi*r

2*pi*r = 44

r = 44/(2pi)

r = 7.0028175 which is approximate

--------------------

Now plug this into the formula for the area of a circle

A = pi*r^2

A = pi*(7.0028175)^2

A = 154.061985

A = 154 rounding to the nearest whole number

Answer:

B

Step-by-step explanation:

Circumference = 2πr

And circumference = 44 m

44 = 2πr

so, r = 44/2π

r = 22/π

Radius is 22/π

Area of circle = πr²

Area of circle = π × (22/π)²

Area of circle = π × 22²/π²

Area of circle = 22²/π

Area of circle = 484/π

Area of circle = 154.14m²

Answer:

Darius needs [tex]26\frac{2}{3}[/tex] cups of bread cubes to make four batches of stuffing for a family reunion.

Step-by-step explanation:

Given:

bread cubes to make a batch of stuffing  =   6 2/3 cup

To Find:

Number of cups of bread cubes needed to make four batches of stuffing for a family reunion = ?

Solution:

According to the question, to make one batch of stuffing Darius needs [tex]6\frac{2}{3}[/tex] cups of bread cubes

So if he wants to make four batched, then the number of cups of bread cubes  will be four times  as needed for making one batch

Then

Number of cups of bread cubes needed to make four batches = 4 x  bread cubes needed to make a batch of stuffing

Number of cups of bread cubes needed to make four batches

=  [tex]4 \times 6\frac{2}{3}[/tex]

=>[tex]4 \times \frac{18+2}{3}[/tex]

=> [tex]4 \times \frac{20}{3}[/tex]

=>[tex]\frac{80}{3}[/tex]

=>[tex]26\frac{2}{3}[/tex]

Darius will need 80/3 cups of bread cubes to make four batches of stuffing for a family reunion.

To find out how many cups of bread cubes Darius will need to make four batches of stuffing for a family reunion, we need to multiply the amount of bread cubes used in one batch by the number of batches he wants to make. Darius uses 6 2/3 cups of bread cubes in one batch. So, to find the total amount of bread cubes needed for four batches, we can multiply 6 2/3 cups by 4.

First, we convert the mixed number into an improper fraction: 6 2/3 = (6 * 3 + 2)/3 = 20/3.

Next, multiply the improper fraction by 4: (20/3) * 4 = 80/3 cups.

Therefore, Darius will need 80/3 cups of bread cubes to make four batches of stuffing for a family reunion.

After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today

Step-by-step explanation:

Let's calculate the change in temperature after 4 days, this way:

Today's temperature = t in Fahrenheit degrees

Tomorrow's temperature = t - 3/16 Fahrenheit degrees

The day after tomorrow's temperature = t - 2 * 3/16 = t - 3/8 Fahrenheit degrees

Therefore, the temperature after 4 days will be = t - 4 * - 3/16 = t - 3/4 Fahrenheit degrees

After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today

Answer:3√(p/q)3

Step-by-step explanation: Find the cube root .

The law used to simplify the expression [tex]( (p/q)^3 \)[/tex] is the "Power of a Quotient" rule.

The correct option is (b).

The "Power of a Quotient" rule states that when a fraction is raised to a power, we can raise both the numerator and denominator to that power individually. Mathematically, it is represented as:

[tex]\[ \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n} \][/tex]

Applied to the expression [tex]\( (p/q)^3 \)[/tex], we raise both[tex]\( p \) and \( q \)[/tex] to the power of 3:

[tex]\[ \left(\frac{p}{q}\right)^3 = \frac{p^3}{q^3} \][/tex]

This simplification allows us to express the original expression in terms of powers of the numerator and denominator separately. In other words, the exponent 3 is distributed to both [tex]\( p \) and \( q \), resulting in \( p^3 \)[/tex]in the numerator and [tex]\( q^3 \)[/tex] in the denominator.

Using this rule, we can handle expressions involving powers of fractions efficiently, breaking them down into simpler terms that are easier to work with or evaluate. It's particularly useful when dealing with algebraic expressions or equations where fractions with powers are involved, providing a systematic approach to simplification.

Answer: [tex]x=-25[/tex]

Step-by-step explanation:

For this exercise it is necessary to remember the multiplication of signs:

[tex](+)(+)+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then, having the following equation provided in the exercise:

[tex]4 + \frac{1}{5}x = -1[/tex]

You need to solve for the variable "x" in order to find its value.

To solve the equation, you can follow the steps shown below:

Step 1: You need to subtract 4 from both sides of the equation. Then:

[tex]4 + \frac{1}{5}x-(4) = -1-(4)\\\\ \frac{1}{5}x=-1-4\\\\ \frac{1}{5}x=-5[/tex]

Step 2: This is the final step. You must multiply both sides of the equation by 5 in order to find the value of the variable "x".

Then, you get the following result:

[tex](5)( \frac{1}{5}x)=(-5)(5)\\\\x=-25[/tex]
