Annie was going to use the elimination method. She was ready to add the same value to both sides of the equation to eliminate the x-terms when she noticed a problem: Both x-terms are positive!
2x+7y=13
2x+3y=5

Rather than adding the equations together, how else could you eliminate the x-term? Once you have figured out a method, solve the system and check your solution.

Find the surface area of a square pyramid with side length 3 cm and slant height 3 cm

Answers

Answer:

Step-by-step explanation:

base length b = 3 in

slant height L = 3 in

base area = b² = 3² = 9 in²

lateral area = 4·½bL = 4·½·3·3 = 18 in²

surface area = base area + lateral area = 27 in²

Answers

You see how y=4x and the left side on the table is x and the right side is y you plug whatever number is on the x side into the -4x
For example let’s do the first one y=-4(9) -4 multiplied by 9 is 36 so y=36 so you put 36 in the first box on the right (y side)

Answer:

1) (-36)

2) 4

3) (-4)

4) (-20)

5) (-12)

Step-by-step explanation:

See, above it written that y = (-4)x

Then below they are giving the value of x

So, according to that we have to solve the value y

For example:

y = (-4) x 9

y = (-36)

1 - As células da bactéria Escherichia coli têm formato cilíndrico, com 8 x 10−7 metros de diâmetro. O diâmetro de um fio de cabelo é de aproximadamente 1 x 10−4 metros. Dividindo-se o diâmetro de um fio de cabelo pelo diâmetro de uma célula de Escherichia coli, obtém-se, como resultado a) 200. B) 135 . C) 140. D) 125.

Answers

Answer:

125

Step-by-step explanation:

The cells of the bacterium Escherichia coli have a cylindrical shape, with 8 x 10−7 meters in diameter. The diameter of a hair is approximately 1 x 10−4 meters. Dividing the diameter of a hair by the diameter of a cell of Escherichia coli gives, as a result, a) 200. B) 135. C) 140. D) 125

We are carrying out division operation

The diameter of a hair ÷ The diameter of a cell of Escherichia

The cells of the bacterium Escherichia coli have a cylindrical shape = 8 x 10^−7 meters in diameter.

The diameter of a hair is approximately 1 x 10^−4 meters

Therefore:

1 x 10^−4 meters ÷ 8 x 10^−7 meters

= 125

Bryn is riding his bicycle at a constant speed from school to the library. His distance from the library in kilometers x hours after leaving school can be modeled by the equation Y=20-12X. What is the distance between the school and the library in kilometers?

Answers

Answer:

The distance is 20km

Step-by-step explanation:

Given

[tex]y = 20 - 12x[/tex]

Required

The distance between [tex]the\ library\ and\ the[/tex] school

The function represents the distance [tex]y = 20 - 12x[/tex]

So, when x = 0.

This implies that he has not started moving.

So:

[tex]y = 20 - 12 * 0[/tex]

[tex]y = 20 - 0[/tex]

[tex]y = 20[/tex]

At 11:45 A.M. Jason glanced at the clock. His doctor's appointment was in 2 ½ hours. At what time was his appointment

Answers

Answer:

14 : 15 or 2 : 15 pm

Step-by-step explanation:

Time of the appointment = 11: 45 +  2 ½ hours

Jason's appointment is in  2 ½ hours. His appointment is in 2 hours + 1/2 of an hour

1/2 of an hour = 1/2 x 60 = 30 minutes

Remember that 60 minutes make one hour

Time of the appointment = 11:45 + 2:30

 [tex]11 : 45[/tex]

+ 2 : 30

 13 :  75

we would have to adjust the time derived from the addition because the maximum minutes that exist is 60

To adjust, remove 60 minutes from the minutes and add it to the hour

this gives 14 : 15 or 2 : 15 pm

People of the past and present judge each other by their class. This could relate to how much wealth they have as well as their social class or economic status. These judgements separate us as a society and live our lives around these judgments. Class in simple words is a group of people or things categorized by the quality and economic status. This relates to the novel "The Great Gatsby" by some of the characters in the novel such as Tom and Daisy Buchanan.

Answers

Answer:

This is just how I would write it, dosen't mean it's better, just personal preference

Step-by-step explanation:

People of the past and the present judge each other based on class. This could be a social or an economic status or class difference and these judgements separate us as a society. Class in simple words is a group of people or things categorized by the quality and economic status. This relates to the novel "The Great Gatsby" by some of the characters in the novel such as Tom and Daisy Buchanan.

I don't know why you are defining class here but there might be some context I'm missing. In most scenarios though, defining a term is not a priority and is defentetly making the introduction run on for a while.

I would add a sentence before the last sentence futher tying in what your introduction has to relate with the book or at least some words like: "and this is shown in the Great Gabsy" or something like that
