Answer:

Step-by-step explanation:

For those 2 lines to parallel to each other, then the 2 angles have to be alternate interior and have to be congruent. The value of x that makes them congruent is found by setting the 2 expressions equal to each other and solving for x:

$6x+42=18x-12$ and

$54=12x$ so

x = 4.5

Answer:

4.5

Step-by-step explanation:

The two angles are equal

This means that: 6x + 42 = 18x - 12

Rearrange the equation to get x on one side and the integers on the other.

42 + 12 = 18x - 6x

54 = 12x

54/12 = x

x = 9/2 = 4.5

What is a example of a composite figure in your home or community? How would you decompose it to find the area? Can you think of

Answer: An L-shaped room in your house

Imagine any room in your house that is not just a single rectangle, square or other shape. This would be an example of a composite shape. It simply means that it is made up of more than one shape.

For example, if you had a living room in the shape of an L. This would be a composite shape because you would have to put 2 rectangles together to make the shape.

asambeis [7]

Step-by-step explanation:There's a hundred and four days of summer vacation

'Til school comes along just to end it

So the annual problem for our generation

Is finding a good way to spend it

Like maybe

Building a rocket or fighting a mummy

Or climbing up the Eiffel Tower

Discovering something that doesn't exist

Or giving a monkey a shower

Surfing tidal waves, creating nanobots

Or locating Frankenstein's brain

Finding a dodo bird, painting a continent

Or driving our sister insane

This could possibly be the best day ever

And the forecast says that tomorrow will likely be

A million and six times better

So make every minute count

Jump up, jump in and seize the day

And let's make sure that in every single possible way

Today is gonna be a great day

Crossing the tundra or building a roller coaster

Or skiing down a mountain of beans

Devising a system for remembering everything

Or synchronizing submarines

Racing chariots, taming tiger sharks

Constructing a portal to Mars

Building a time machine, stretching a rubber tree

Or wailing away on guitars

This could possibly be the best day ever

And the forecast says that tomorrow will likely be

A million and six times better

So make every minute count

Jump up, jump in and seize the day

And let's make sure that in every single possible way

Today is gonna be a great day

Let's put our heads together and design a master plan

We may miss dinner but I know mom will understand

We've got our mission and some pliers

Yogurt, gumballs and desire

And a pocketful of rubber bands

The manual on handstands

A Unicycle, compass

And a camera that won't focus

And a canteen full of soda

Grab a beach towel

Here we go!

This is Ferb-tastic!

This could possibly be the best day ever

And the forecast says that tomorrow will likely be

A million and six times better

So make every minute count

Jump up, jump in and seize the day

And let's make sure that in every single possible way

Seriously, this is gonna be great!

This could possibly be the best day ever

Today is gonna be a great day

This could possibly be the best day ever

5. A 12-ounce jar of jam costs $2.40. A 16-ounce jar costs $4.00. What is the

scoray [572]

The difference in the cost per ounce is $0.05 per ounce

<h3>Fractions and proportion</h3>

Fractions are written as the ratio of two integers

If a 12-ounce jar of jam costs $2.40, the cost per ounce will be:

Unit cost = 2.40/12

Unit cost = $0.2

Similarly, if a 16-ounce jar costs $4.00, the price of a ounce will be:

Unit cost = 4/16

Unit cost. =$0.25

difference = $0.25 - $0.2

difference = $0.05

Hence the difference in the cost per ounce is $0.05 per ounce

It takes 313131 employees and \$7500$7500dollar sign, 7500 to build a car, and it takes 191919 employees and \$4300$4300dollar s

Rainbow [258]

Complete question :

It takes 313131 employees and \$7500$7500dollar sign, 7500 to build a car, and it takes 191919 employees and \$4300$4300dollar sign, 4300 to build a motorcycle. Genghis Motors wants to spend more than \$84000$84000dollar sign, 84000 to build cars and motorbikes using at most 706706706 employees. Let CCC denote the number of cars they build and MMM the number of motorbikes they build. Write an inequality that represents the condition based on the number of employees. Write an inequality that represents the condition based on the number of dollars.

Answer:

31C + 19M ≤ 706

7500C + 4300M > 84000

Step-by-step explanation:

C = number of cars built

M = number of motorcycles built

Cost of building a car :

Cost = 31 + $7500

Cost of building a motorcycle,:

Cost = 19 + 4300

To build, C cars :

Number of employees = 31C

7500 * C = 7500C

To build, M motorcycles :

Number of employees = 19M

4300 * M = 4300M

Genghis budget :

Amount > 84000

Number of employees ≤ 706

Hence, the constraints

31C + 19M ≤ 706

7500C + 4300M > 84000
