8x+21=3 need the answer please

Mathematics
1 answer:
GarryVolchara [31]2 years ago
3 0

Answer:

x=-\frac{9}{4}

Step-by-step explanation:

<u>Step 1:  Subtract 21 from both sides</u>

8x + 21 = 3

8x + 21 - 21 = 3 - 21

8x = -18

<u>Step 2:  Divide 8 from both sides</u>

8x = -18

\frac{8x}{8}=-\frac{18}{8}

x=-\frac{9}{4}

Answer:  x=-\frac{9}{4}

Jessie has a container that contains 18 3/4 cios of ice cream. How many 1/3-cup servings of ice cream are in the container
ladessa [460]

Hi there!

18 × \frac{3}{4} = amount of ice cream in container

13.5 = amount of ice cream in container


Let's replace the number of cups by "C" :

13.5 = C × \frac{1}{3}

Isoltate "C" by dividing each side of the equation by \frac{1}{3}


40.5 = C


Which means that your answer is : There are 40.5 1/3-cup servings of ice creamin the container!


There you go! I really hope this helped, if there's anything just let me know! :)

The research shows that the name of the ferris wheel is <u>The London Eye</u> and the diameter of the wheel is 120m.

<h3>What is a research?</h3>

A research is simply carried out to get information about a particular topic or issue.

In this case, the research was conducted on the ferris wheel. The number of cars or compartments is 32.

The circumference of the wheel will be:

= 2πr

= 2π(120/2)

= 377m

The area of the wheel will be:

= πr²

= π(60²)

= 11310m²

The measure of a central angle in degrees will be:

= 360/32 = 11.25 degrees

The measure of a central angle in radians will be:

= 2π(11.25)/360

= 20 radians.

The arc length between two cars or compartments will be:

= 2π(60)(11.25)/360

= 11.78

The area of a sector between two cars or compartments will be:

= π(60²)(11.25)/360

= 353.43

An equation of a circle for your ferris wheel when the center of the ferris wheel is located at (0, 0) on a coordinate grid will be x² + y² = 3600.

Help plz I need help ASAP!!!!!!!!!!!!!!!!!!!

So, each square on the grid is 10 inches in length and width

To find the dimension of the diagonal lengths, treat them like a hypotenuse so we can use the Pythagorean theorem.

a^2 + b^2 = c ^2

a and b are our length and width and c is the hypotenuse.

Make each diagonal length part of a triangle. There will then be 4 triangles to work with.

Triangle 1 (Top left)

Triangle 2 (Bottom left)

Triangle 3 (Top Right)

Triangle 4 (Bottom Right)

A right triangle made with the top left diagonal dimension will have a vertical dimension of 30 (10+10+10) and a horizontal dimension of 40 (10+10+10+10)

To find c or the hypotenuse, plug these into the Pythagorean theorem.

30^2 + 40^2 = c ^2

c^2 = 900 + 1600 = 2500

c = sqrt(2500) = 50

You will see that triangles 2, 3, and 4 have the same vertical and horizontal dimensions giving them the same value.

Now combine the dimensions

diagonal = 50+50+50+50 = 200

horizontal = 90+90 = 180

diagonal + horizontal = 380
