Answer:

Step-by-step explanation: Let variable x represent the 15¢ stamps, and variable y represent 20¢ stamps.

x= 3y-8

0.15x+0.20y = 4

Replace x in the second equation by (3y-8)

0.15(3y-8) + 0.20y = 4

0.45y - 1.2 +0.20y = 4

Collect like terms;

0.45y+0.20y = 4+1.2

0.65y = 5.2

Divide both sides by 0.65 to solve for y;

y= 5.2/0.65

y = 8

Replace in equation " x=3y-8 " to solve for x;

x = (3*8) -8

x=24 - 8

x = 16

Therefore, the 15¢ stamps are 16 in number, and the 20¢ stamps are 8 in number.

Answer:

D) 12.25x+3.99=77.49

Step-by-step explanation:

Each shirt costs $12.25, so that means 12.25 times x the amount of shirts. Then, you add the $3.99 shipping amount. All of this adds up to 77.49.

So the answer would be D.

Answer:

D. 12.25x +3.99 = 77.49

Step-by-step explanation:

We don't know the amount of shirts Mrs. Garfield order, so we can assume that the amount of shirts is x.

We know the amount per shirt, so we can assume the total cost for the shirts is  12.25x

The problem also explained that there was a 3.99 shipping cost, so our equation would look like this.

12.25x+3.99

Lastly, we are told the total cost of the shipment. The total cost is 77.49. Since, 12.25x+ 3.99 is supposed to be the same as 77.49, the equation should look like this.

12.25x +3.99 = 77.49

Final Equation:

12.25x +3.99 = 77.49

This is the same answer as D. on the worksheet.

The red dot and arrow are the solutions. The solid dot means the number is included. So it is equal to -5, the arrow is going to the right, so it is also greater than -5

Answer:

8 books

Step-by-step explanation:

12/3= 4

12-4 = 8

There are 8 books does Andy check out.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Angel checks out 12 library books and Andy checks out 1/3​ less than that.

Now,

Since, Angel checks out 12 library books and Andy checks out 1/3​ less than that.

Hence, The number of books for Andy = 12 - 1/3 of 12

                                                            = 12 - 1/3 × 12

                                                            = 12 - 4

                                                            = 8

Thus, There are 8 books does Andy check out.

Answer: Many researchers, engineers and environmentalists are expressing deep concerns about changes in the overall climate of the planet. Fossil fuels are being continuously used to produce electricity. The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming. Deforestation is also leading to warmer temperatures. The hazard of global warming is continuously causing major damage to the Earth's environment. Most people are still unaware of global warming and do not consider it to be a big problem in years to come. What most people do not understand is that global warming is currently happening, and we are already experiencing some of its withering effects. It is and will severely affect ecosystems and disturb ecological balance. Because of the treacherous effects of global warming, some solutions must be devised. The paper introduces global warming, elaborates its causes and hazards and presents some solutions to solve this hot issue. Above all, alternative energy sources (solar, wind, hydro, geothermal, bio mass) need to be seriously pursued. Finding and using renewable sources of energy is one of the methods to combat the ever increasing global warming effectively.

y = 8x – 25

Step-by-step explanation:

Answer:

8x-25=y

Step-by-step explanation:

All we need is slope. (y2-y1)/(x2-x1). Now we just substitute values--(7+1)/1=8

Now we can plug in the slope as m, so

8x+b=y

Now all we have to do is plug in a point value and find B.

24+b=-1

Subtract 24 from both sides

b=-25
