Three is six less than one-third the number p

Answer:

[tex]x=\frac{3j-n}{4k+7m}[/tex]

Step-by-step explanation:

We have the expression [tex]3j=4kx+7mx+n[/tex] and we have to solve for x, this means that we have to clear x.

Then first we are going to subtract n in both sides of the equation,

[tex]3j=4kx+7mx+n\\3j-n=4kx+7mx+n-n\\3j-n=4kx+7mx[/tex]

Now in the right side we can apply common factor x.

[tex]3j-n=(4k)x+(7m)x\\3j-n=x(4k+7m)[/tex]

For the last step divide both sides of the equation in (4k+7m),

[tex]3j-n=x(4k+7m)\\\\\frac{3j-n}{4k+7m}=\frac{x(4k+7m)}{(4k+7m)} \\\\\frac{3j-n}{4k+7m}=x[/tex]

Then,

[tex]x=\frac{3j-n}{4k+7m}[/tex]

Step-by-step explanation:

The student can check the accuracy of their answer by substitifying their solution back into the equation. If both sides of the equation are equal after the substitution, then the solution is correct and 4 * 3 + 6 does in fact equal 18 in this case.

The subject of your question is to solve a simple equation and you want to check your answer. The equation you're talking about can be expressed as 4x + 6 = 18, where x is the number you're trying to find. You said you believe x = 3, and we can check that by substituting 3 for x in the equation and seeing if both sides match.

On the left side of the equation, 4x + 6 would become 4 * 3 + 6, which equals 12 + 6 = 18. The right side of the equation is also 18, so your answer of x = 3 is correct!

Substituting your answer back into the equation is a solid strategy to check your answers in mathematics.

To determine which package is a better deal, we need to compare the price per bar of soap for each package. The second package is the better deal as it has a lower price per bar of soap.

The question is asking about the comparison of two different packages of soap based on their price and quantity. To determine which package is a better deal, we need to calculate the price per bar of soap for each package.

For the first package, we have 12 bars of soap for $10.00. To find the price per bar, we divide the total cost by the number of bars: $10.00 ÷ 12 = $0.83 per bar.

For the second package, we have 5 bars of soap for $4.00. Again, we divide the total cost by the number of bars: $4.00 ÷ 5 = $0.80 per bar.

Comparing the prices per bar, we can see that the second package is cheaper, so it is the better deal.

If product of x and 5.2 is 104 then the value of x is 20.

Two or more expressions with an Equal sign is called as Equation.

Given that  product of x and 5.2 is 104

We have to find the value of x

product of x and 5.2 is 104 can be mathematically written as below

5.2x=104

To find value of x

divide both sides by 5.2

x=104/5.2

x=20

Hence, if product of x and 5.2 is 104 then the value of x is 20.

Answer:

The answer is 2.4%

Step-by-step explanation:

After subtracting the cost of one bunch of baby's breath ($3.50) from the total budget ($16), you have $12.50 left for the roses. Since each rose costs $2.50, you can buy 5 roses to complete your bouquet within the budget.

To calculate the number of roses that can be bought, first, we need to subtract the cost of one bunch of baby's breath from the total budget for the bouquet. The cost of one bunch of baby's breath is $3.50. With a total budget of $16, we subtract the cost of baby's breath to see how much is left for the roses:

$16.00 - $3.50 = $12.50

Since each rose costs $2.50, we will divide the remaining budget by the cost of each rose to find out the number of roses that can be purchased:

$12.50 / $2.50 = 5 roses

Therefore, you can buy 5 roses along with one bunch of baby's breath to make up your $16 bouquet.

Answer: The system of equations have many solutions and the correct options are A,B and D.

Explanation:

The given equations are,

[tex]2x+y=5[/tex]     ..... (1)

[tex]3y=15-6x[/tex]  .... (2)

Simplify the second equation.

[tex]3y+6x=15[/tex]

[tex]3(y+2x)=15[/tex]

Divide both sides by 3.

[tex]2x+y=5[/tex]

It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.

Test the points whether the point lies on the line or not.

Check for point A(6,-7).

[tex]2(6)+(-7)=5[/tex]

[tex]5=5[/tex]

LHS and RHS are equal, therefore the point A is the solution of the system of equations.

Check for point B(2,1).

[tex]2(2)+(1)=5[/tex]

[tex]5=5[/tex]

LHS and RHS are equal, therefore the point B is the solution of the system of equations.

Check for point C(-2,-9).

[tex]2(-2)+(-9)=5[/tex]

[tex]-13=5[/tex]

LHS and RHS are not equal, therefore the point C is not the solution of the system of equations.

Check for point D(-4,13).

[tex]2(-4)+(13)=5[/tex]

[tex]5=5[/tex]

LHS and RHS are equal, therefore the point D is the solution of the system of equations.

Therefore the options A,B and D are correct.

The points (6, –7), (2, 1), and (–4, 13) satisfies the equation and hence, will be the solution of the equation. The correct solution for this system is A, B, and D.

Given:

Final answer:

The mass of the 5.50 cm³ cylinder of a substance with a density of 4.20 g/cm³ is 23.10 g.

Explanation:

To calculate the mass of the cylinder, you can use the formula: Mass = Density x Volume.

Given that the density of the substance is 4.20 g/cm³ and the volume of the cylinder is 5.50 cm³, you can substitute these values into the formula to find the mass.

Mass = 4.20 g/cm³ x 5.50 cm³ = 23.10 g.

The mass of the cylinder with a volume of 5.50 cm³ and a density of 4.20 g/cm³ is calculated using the formula Mass = Density × Volume, which results in a mass of 23.1 grams.

To calculate the mass of a cylinder of a substance when the volume and density are known, use the formula:

Mass = Density × Volume

Given that the density of the substance is 4.20 g/cm³ and the volume of the cylinder is 5.50 cm³, we can substitute these values into the formula:

Mass = 4.20 g/cm³ × 5.50 cm³

Mass = 23.1 g

The mass of the substance is 23.1 grams. It's important to note that the result should be reported with the appropriate number of significant figures. The original volume was given to three significant figures, so the final answer should also reflect three significant figures.
