Question: -3x – 10 = 32

Answers

Answer 1

Answer:

x = -14

Step-by-step explanation:

The first thing you are trying to do is get the x alone. so first you will look at 10 and do the opposite of the sign that you have. So you would take the -10 and make it +10. you would solve -10 + 10 and 32 + 10 because whatever you do to one side you do to the other. -10 +10= 0 and 32+10 = 42. Your equation now is -3x=42. we do not put -3x+0=42 because zero does not have a value. From here we would look at the -3x and do the opposite sign, which means dividing. whenever a number is next to x or any variable it is multiplication. For example, 7x is the same as 7*x. The opposite of multiplication is division. so we would do -3x/-3. We do 42/-3 because whatever we do to one side we do to the other. On the left side we are left with x then you add the equal sign and the quotient of 42/-3.

Answer: x = -14

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 240 ninth-graders at a high school are divided into homeroom groups of 10 or 12 students. This equation models the
situation, where x represents the number of 10-student groups and y represents the number of 12-student groups:
10x +12y = 240.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.
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%

Hence, The mass/volume percent is 32%.

On a number line, what other number is the same distance from -2.8 as -7.2 is?​

Answers

Answer;

1.6

Explanation

What we shall do here is to calculate the distance between the two points on the number line

Mathematically, that would be ;

-2.8 -(-7.2) = -2.8 + 7.2 = 4.4

This means that -7.2 is 4.4 units away from -2.8

So to find other number which is this same distance;

we have -2.8 + 4.4 = 1.6

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.
