Answer:

6(7m+2)=42m+12

Step-by-step explanation:

Step 1: Distribute the 6 to 7m and 2. So, 6 x 7m = 42m

Answers

Answer:

y - 3 = (1/2)(x - 4)

Step-by-step explanation:

The graph is hard to read, but we can make assumptions about the x- and y-values shown.  The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3).  Let's try finding the equation of the line using this assumed data:

The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

We need the slope of the line.  Recall that m = rise/run.  Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2.  Thus, the slope is m = rise/run = 2/4, or 1/2.

Substituting the known values into the point-slope equation y - k = m(x - h), we get:

y - 3 = (1/2)(x - 4)

The sunshine ski shop makes a profit of $40 on each pair of skis sold. Shop expenses for one week are 2,480. What is the minimum number of pairs of skis that must be sold in one week to make profit of at least $2,000

Answers

Answer:

Number of units to sell= 112 units

Step-by-step explanation:

Giving the following information:

Unitary contribution margin= $40

Fixed costs= $2,480

Desired profit= $2,000

To calculate the number of units to be sold, we need to use the following formula:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= (2,480 + 2,000) / 40

Break-even point in units= 112 units

Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice point is a point such that both of its coordinates are integers). How many times does he label a point with the number $25$?

Answers

Answer:

4 times

Step-by-step explanation:

A lattice point may be defined as the point of intersection of two grid lines or more than two grid lines that is placed in a regularly spaced points arrays. This is called a lattice point.

In the context, Chris tries to label every lattice point in a coordinate plane with its square of distance from the point to its origin. The lattice points means that the numbers are both the integers. So for number 25, Chris has to label 4 times

What would an equation be for a line with a slope of 3 and a y-intercept of 7?

Answers

Answer:

y = 3x + 7

Step-by-step explanation:

Using the formula y = mx + b we can create this equation.

m = slope

b = y -intercept

based on the information provided I know that

Slope = 3

and

y-intercept = 7

Substitute:

y = mx + b

y = 3x + 7

y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.

Let us use the slope-intercept form for this, with m as the slope and b as a constant.

y = mx + b

7 = 3(0) + b  [since the y-int is 7, the x value will be zero]

b = 7

y = 3x + 7

how many solutions does 6x - 18 = 4(2x - 3) - (2x +6)

Answers

Answer:

x=0

Step-by-step explanation:

6x-18=4(2x-3)-(2x+6)

We move all terms to the left:

6x-18-(4(2x-3)-(2x+6))=0

We calculate terms in parentheses: -(4(2x-3)-(2x+6)), so:

4(2x-3)-(2x+6)

We multiply parentheses

8x-(2x+6)-12

We get rid of parentheses

8x-2x-6-12

We add all the numbers together, and all the variables

6x-18

Back to the equation:

-(6x-18)

We get rid of parentheses

6x-6x+18-18=0

We add all the numbers together, and all the variables

=0

x=0/1

x=0

BOATING Dedra's boat used 5 gallons of gasoline in 4 hours. At this rate, how many gallons of gasoline will the boat use in 10 hours?

Answers

The number of gallons of gasoline that the boat will use in 10 hours is 12.5 gallons

If Dedra's boat used 5 gallons of gasoline in 4 hours, this is expressed as:

5 gallons = 4 hours

In order to know the number of gallons needed in 10 hours, this is expressed as:

x = 10 hours

Divide both expressions:

5/x = 4/10

4x = 50

x = 50/4

x = 12.5 gallons

Hence the number of gallons of gasoline that the boat will use in 10 hours is 12.5 gallons

0.5 e + 20= 25


solving equations

Answers

Answer:

e = 10

Step-by-step explanation:

Simplifying

0.5e + 20 = 25

Reorder the terms:

20 + 0.5e = 25

Solving

20 + 0.5e = 25

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-20' to each side of the equation.

20 + -20 + 0.5e = 25 + -20

Combine like terms: 20 + -20 = 0

0 + 0.5e = 25 + -20

0.5e = 25 + -20

Combine like terms: 25 + -20 = 5

0.5e = 5

Divide each side by '0.5'.

e = 10

Simplifying

e = 10

Answer:

e = 1

Step-by-step explanation:

0.5e + 20 = 25

0.5e = 5

e = 1

You subtract 20 from 25 to get 5. Then you divide 5 by 5 to get e = 1

  m∠CAB = 62°

  m∠CBG = 114°

Step-by-step explanation:

Given:

  the above figure

Find:

  What are the measures of angles CAB and CBG

Solution:

The total angle at C is 32°+52° = 84°. We know that "remote interior" angles ECB and EBE have a sum that matches angle CEF.

So, angle CBE = 150° -84° = 66°

Angle CBG is the supplement of this, so is ...

  m∠CBG = 180° -66° = 114°

That angle is the total of "remote interior" angles BCA and CAB. So angle CAB is ...

  m∠CAB = 114° -52° = 62°

There is a blue lining around the earth called earths atmosphere, and that blue protects us from the suns harmful rays, keeps us from freezing during the cold seasons, and protects us from space (as you may know space does not have oxygen to where humans can breath normally). Wait what was that.. What can you do to stop adding greenhouse gases to the earth? Well thats exactly what I am going to educate you on. So just sit back and pay attention.So as I said adding too much greenhouse gases puts animals and humans in danger. I know what your thinking. How bad can greenhouse gases be to put animals and humans in danger. Actually, it is so bad it adds heat to the earth and even when its hot enough already. Every year it feels hotter and hotter in the summer. Thats because humans are adding the greenhouse gases to the earths atmosphere. In fact, most humans are adding greenhouse gases to the atmosphere without knowing it. If you think about it, the bigger our population: the more resources we need to live. One of the biggest resources humans need to live is energy. Most of the things we use everyday uses energy. For example: light, cars, cell phones, computers, TVs, and video games. There is more than that but that is all I can think of for now. The greenhouse effect is a natural process that causes the earth to warm up. This process involves the sun and many gases in our atmosphere.Our energy comes from fossil fuels, which is oil, coal, and natural gas. Fossil fuels are an important resource for energy. Fossils are formed when plants and animals die and are covered in sediment and pressed for many thousands of years. Climate change is very dangerous. That is why I need to explain to you what you can do around and in your home to help stop global warming. Global warming is a process that is caused by fossil fuels, greenhouse gases, and the greenhouse effect. So listen carefully if you are interested in knowing how to stop global warming starting with you. The biggest factor of climate change is the use of energy which as I said is made from the burning of fossil fuels. So when you are at home and a light or the TV is on and it is not in use it would be a big help to turn it off and conserve energy within your home. Carbon dioxide is a harmful gas to humans and animals so planting some trees or flowers also helps a lot. When you are driving it adds more greenhouse gas because you use fuel to fill up your tank, so using a public transportation or riding a bike will help more than anything else when you are outside. When you are in the kitchen cooking (I know even cooking adds greenhouse gases to the earth) using a toaster or a microwave to cook some food will save much more energy than using an oven . Another big way that energy is used within your kitchen is a dishwasher. Dishwashers use a lot of water and produce a lot of heat, so hand washing a drip drying your dishes is a much more easier way to save energy. And last but not least when your at school recycling stuff that can be recycled instead of throwing it away is also a way you can help stop global warming. Making sure the computers you use in your classroom are all off or on sleep mode when not in use is a even better way to help in school. But the most helpful when trying to help stop global warming is riding your bike or skateboard to school instead of asking your parents for a ride. So I hope you enjoyed my essay and remember helping stop global warming is a good deed many people dont think of. Save energy the best you can and have a wonderful day! Fill in the blanks.
