sole the equation. check your solution 2.5 y + 6=4.5y-1 ​

Answers

Answer 1

Answer:

3.5 = y

Step-by-step explanation:

2.5y + 6 = 4.5y - 1

2.5y + 7 = 4.5y

7 = 2y

3.5 = y

Check:

2.5y + 6 = 4.5y - 1

2.5(3.5) + 6 = 4.5(3.5) - 1

2.5(3.5) + 7 = 4.5(3.5)

8.75 + 7 = 15.75

15.75 = 15.75

Answer 2

Answer:

[tex]y=3.5[/tex]

Step-by-step explanation:

[tex]2.5y+6=4.5y-1[/tex]

Start by subtracting [tex]6[/tex] from both sides of the equation:

[tex]2.5y=4.5y-7[/tex]

Subtract [tex]4.5y[/tex] from both sides of the equation:

[tex]-2y=-7[/tex]

Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]-2[/tex]:

[tex]y=3.5[/tex]

_

Check your solution by substituting the solved value of [tex]y[/tex] ([tex]3.5[/tex]) into the initial equation:

[tex]2.5(3.5)+6=4.5(3.5)-1[/tex]

[tex]8.75+6=15.75-1[/tex]

[tex]14.75=14.75[/tex]

Since both sides of the equation are equal to each other, our solution is correct!

Answers

Answer:

The degree of the given polynomial is 5

Step-by-step explanation:

The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.

The degree of a monomial is the sum of the exponents of the variables that appear in it.

We have the following polynomial:

[tex]3x^2y + 4xy + 1 - 5x^4y - 6y[/tex]

Degree of the first monomial: 2+1=3

Degree of the next monomial: 1+1=2

Degree of the next monomial: 0

Degree of the next monomial: 4+1=5

Degree of the next monomial: 1

Thus, the degree of the given polynomial is 5

You invest $1000 in an account that has an annual interest rate of 4%, compounded monthly for 12 years. What is the equivalent interest rate and how many times will the money be compounded?
0.33% and 1 time
3% and 4 times
3% and 144 times
0.33% and 144 times

Answers

Answer:

The final balance is $1,612.23.

The total compound interest is $612.23.

Step-by-step explanation:

The required equivalent interest rate and money compounded is 0.33% and 144 times respectively. Option b is correct.

Equivalent interest rate for 4% and how many times the money will be compounded to be determine.

What is arithmetic?

In mathematics it deals with numbers of operations according to the statements.

Here, the equivalent interest rate = 4%/12
                                                     
= 1/3
                                                     = 0.33%


Now, number of times money compounded = 12 years
                                                                    = 12 x 12 months
                                                                    = 144

Thus, the required equivalent interest rate and money compounded is 0.33% and 144 times respectively.

I NEED HELP ASAP PLEASE!! -4(w+1)=-24 w= what?

Answers

GiveN:

-4(w + 1) = -24w

What to do?

We have to solve for w

Step-by-step explanation:

For solving the Equation, we need to simplify it first. Expanding the parentheses.

⇒ -4w - 4 = -24 w

Shifting -24 w to the LHS to isolate m and shifting 4 to the RHS[tex].[/tex]

⇒ -4w + 24w = 4

⇒ 20w = 4

Dividing the equation by 20, So that we will get w in the LHS of the equation.

⇒ w = 4/20

⇒ w = 1/5

The required value of w is 1/5.

4d = txy

Answers

Answer:

[tex]\huge\boxed{x=\frac{4d}{ty}}[/tex]

Step-by-step explanation:

If we have an equation ([tex]4d=txy[/tex]) and we want to solve for x, we want to reverse the equation until we have x on one side. Basically - what's stopping x from being alone?

The answer would be the t and the y that are being multiplied by x. So we can divide both sides by t and y to get our answer.

This is the same as dividing both sides by [tex]ty[/tex].

[tex]4d \div ty = txy \div ty[/tex]

[tex]\frac{4d}{ty}=x[/tex]

The x-intercept is located at ( ,0).
The y-intercept is located at (0, )
The slope of the line represented by this equation is[ ]

Answers

Answer: The X intercept is located at (24,0) The Y intercept is located at (0,20)

The slope of the line represented by this equation is -5/6

Step-by-step explanation:

The x-intercept is located at (24, 0).

The y-intercept is located at (0, 20)

The slope of the line represented by this equation is (-5/6).

We have,

Equation:

10x + 12y = 240

This can be written in the slope-intercept form.

y = mx + c

Where m is the slope and c is the y-intercept.

Now,

10x + 12y = 240

12y = 240 - 10x

12y = -10x + 240

y = (-10/12)x + 240/12

y = (-5/6)x + 20

Now,

The y-intercept is 20.

This is when x = 0.

And,

The x-intercept is when y = 0.

0 = (-5/6)x + 20

(5/6)x = 20

x = 4 x 6

x = 24

And,

The slope is (-5/6)

Thus,

The x-intercept is located at (24, 0).

The y-intercept is located at (0, 20)

The slope of the line represented by this equation is (-5/6).

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

Explanation

Given:

Mass of NaCl, m = 16.0 g

Volume of solution, v = 50.0 mL

What to find:

The mass/volume percent.

Solution

The mass/volume percent of the solution can be calculated using the formula below

The mass/volume percent  = mass/volume x 100%

so, we get,

The mass/volume percent

= 16/50 x 100%

= 32%
