2x+3= -15 what is x step by step

Answers

Answer: x = -9

Step-by-step explanation: To solve for x, we first isolate

the term containing x which in this case is 2x.

Since 3 is being added to 2x,

we subtract 3 from both sides of the equation.

On the left, the +3 and -3 cancel out

and on the right, -15 - 3 is -18.

So we have 2x = -18.

Now we can finish things off by dividing

both sides of the equation by 2.

On the left, the 2's cancel and on

the right, -18 divided by 2 is -9.

So we have x = -9 which is the solution to this equation.

A certain drug dosage calls for 17 mg per kg per day and is divided into two doses (1 every 12 hours). If a person weighs 255 pounds, how many milligrams of the drug should he receive every 12 hours? Round your dosage to the tenth of a milligram.

Answers

Answer:

985.15mg

Step-by-step explanation:

Calculation for how many milligrams of the drug should he receive every 12 hours

First step is to calculate the weight in kg

255 lbs = 255/2.2 = 115.9 kg

Second step is multiply mg/kg in order to get total medicine per day

Dose per day=115.9kg × 17 mg

Dose per day= 1,970.3

Third step is to calculate how many milligrams of the drug should he receive by dividing the day dose by 2

Dose milligrams=1,970.3/2

Dose milligrams=985.15mg

Therefore how many milligrams of the drug should he receive every 12 hours will be 985.15mg

The answer is It is between 0 and 1

Step-by-step explanation:

If you solve the problem step by step as (-2^3)^-2<1 then it comes out as true so it would be less than 1 but more then 0.

At a water elevation of 6,391 ft, Mono Lake has a volume of 2,939,000 ac-ft, and a surface area of 48,100 ac. Annual inputs to the lake include 8 in of direct precipitation, runoff from gauged streams of 150,000 ac-ft per year, and ungauged runoff and groundwater inflow of 37,000 ac-ft per year. Evaporation is 45 in per year.

Required:
a. Make a water budget showing inputs, in ac-ftper year and outputs in ac-ft per year. Does the input balance the output?
b. Will the average lake level rise or fall from the 6391ft elevation over the long-term?
c. What would be the lake surface area when the inputs blance the outputs? ( Assume that the volume of gauged and ungauged runoff and ground-water inflows remain constant with a change in lake surface area).
d. What is the residence time for water in Mono Lake when the water surface is at 6391ft?

What is the positive radian measure of the smaller angle formed by the hands of a

clock at 5 o'clock?

Answers

Answer:

the required positive radian measure of the smaller angle is 5π/6 radians or 2.618 radians

Step-by-step explanation:

Given the data in the question;

smaller angle formed by the hands of a clock at 5 o'clock

{at 5 o'clock, two angles are form; 150° and 210°}

hence, the smaller angle is 150°

so, smaller angle = 150° × π/180°

smaller angle = 150°π/180°

smaller angle = 5π/6 radians or 2.618 radians

Therefore, the required positive radian measure of the smaller angle is 5π/6 radians or 2.618 radians

The positive radian measure of the angle formed by the hands of the clock at 5 o'clock is [tex]\frac{5\pi}{6}\text{ radians}[/tex]

In one minute, the long hand makes a full turn equivalent to [tex]2\pi[/tex] radians.

At 1 o'clock, the smaller angle formed by the hands of the clock is

[tex]\dfrac{2\pi\text{ rads}}{12}=\dfrac{\pi}{6}\text{ rads}[/tex]

At 5 o'clock, the smaller angle is five times the one we have when the time is 1 o'clock. That is

[tex]\dfrac{\pi}{6}\text{ radians}\times 5=\dfrac{5\pi}{6}\text{ radians}[/tex]

Find the coordinates for point R that proves figure TRAP is an isosceles trapezoid.

Answers

Answer:b

Step-by-step explanation: I got it right on my test

The coordinates for point R that proves figure TRAP is an isosceles trapezoid is (c - a, b)

From the diagram, we have the following highlights

There are two parallel sides in the trapezoidThe parallel sides of the trapezoid are horizontal lines

This means that the y-coordinate of point R is the same as the y-coordinate of point T.

Given that the y-coordinate of point T is b, the y-coordinate of point R can be represented as:

[tex]R =(x,b)[/tex]

For the shape to be an isosceles trapezoid, then the following must be true

[tex]x = c - a[/tex]

So, we have:

[tex]R =(c - a,b)[/tex]

Hence, the coordinates of R is (c - a, b)

Answers

Answer:

x=21, y=17

Step-by-step explanation:

180-42= 138

2x+138=180

2x= 42

x= 21

8y+2+2x=180

8y+2 + 42=180

8y= 136

y= 17

Answer:

x=21, y=68

Step-by-step explanation:

We're given that the quadrilateral on the left is a parallelogram as indicated by the arrow markings on the sides. We're also told that the angle on the right is 42 degrees. So, we can find the bottom right angle in the parallelogram by subtracting 42 from 180, because it forms a straight angle. 180-42 is 138. By the alternate interior angles theorem, 8y+2=138, because 138 is also the angle measure of the opposite corner. we also know that the bottom left angle in the parallelogram is the same as 2x. by the alternate interior angles theorem. Notice how the sides of the parallelogram with two arrow markings are parallel, which means that the bottom left angle and the 42 degree angle are congruent, or have the same measure, because of the parallel lines. This means that 2x=42, and the bottom left angle is 42. We can solve for x and y with simple algebra now. 8y+2=138, 8y=138-2, 8y=136, y=68. 2x=42, x=42/2, x=21. So, x is 21 and y is 68.

What is the first quartile of the following data set?
15, 18, 20, 21, 23, 24, 26, 29, 34, 37, 40

Answers

Answer:

20.5

Step-by-step explanation:

20 + 21 = 41. Divide 41 by 2 than you get 20.5.

The first quartile of the given data set is 20.

Here,

To find the first quartile of a data set, we first need to arrange the data in ascending order.

Then, we can calculate the position of the first quartile using the formula:

Position of the first quartile (Q1) = (n + 1) / 4

where n is the number of data points in the data set.

Given data set: 15, 18, 20, 21, 23, 24, 26, 29, 34, 37, 40

Arranging the data in ascending order: 15, 18, 20, 21, 23, 24, 26, 29, 34, 37, 40

Now, let's calculate the position of the first quartile:

n = 11 (since there are 11 data points in the data set)

Position of the first quartile (Q1) = (11 + 1) / 4 = 12 / 4 = 3

The first quartile (Q1) is the value at the 3rd position in the ordered data set, which is 20.

So, the first quartile of the given data set is 20.
