This is math can u guys help me with this plss if you have ay questions ask me in the question comment section i just need these two question pls help if you know 8th grade math pls help

Answers

Answer 1

So this may not be correct but I tried so here’s my thought process

1. x - 2y = 3
2. 3x + 2y = 8
3. 2x + 3y = 13
4. 2x - 3y = 19

1. X = 9 Y = 3
2. X = 2 Y = 1
3. X = 2 Y = 3
4. X = 17 Y = 5

The question are vague enough to where anything can be put as x and y. These are just some of those results so do take this with a grain of salt. Good luck?

Answers

Answer:

4 on top three on bottom?

Step-by-step explanation:

Answer:

Hate to break it to you, but it actually is 3

Step-by-step explanation:

You need to make sure 3/4 is equal to the fraction.

It doesn't matter how many slots there are.

The fraction that it's going to be equal to is 9/12

To get the 12 on the bottom, you need to multiply the 4 by 3

Because you want to get an equivalent expression, you have to the same thing to the top. So 3 x 3 is 9.

Both slots are going to have a 3 in it

ahhh i.d.k how to do this pls help

Answers

Answer:

y=-2x-3

Step-by-step explanation:

The set up is always y=mx+b. You have to find m (m is slope) and b (b is y-axis). Since the line goes down, it has a negative slope. From the first point to the second, it goes down 4 and over 2. If you divide 4/2, you get 2 for the slope. The y-axis is just where the point meets the y-axis line and in this example, it meets at -3 so that is your b value.

According to my calculations the correct answer would be y=-2

Answers

Answer:

28j+21

Step-by-step explanation:

7(2j+3+2j)

Times everything in the ( ) by 7.

You should get (14j+21+14j)

Add 14j and 14j together.

And you get the answer.

7(2j+3+2j)

2j x 7 = 14j

3 x 7 = 21

2j x 7 = 14j

(14j + 21 + 14j)

14j + 14j = 28j

28j + 21 is the answer

Greg made a small sign to advertise his school’s activity night. The sign was 15 1/2 inches wide and 11 inches long. Gloria made a longer banner to let students know about the activity night. Her poster was also 15 1/2 wide but it was 44 inches long. How many times larger is the area of Gloria’s banner than Greg’s sign?

Answers

Using the area of a rectangle, it is found that the area of Gloria’s banner is 4 times larger than the area of Greg's sign.

What is the area of a rectangle?

The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex].

For Greg, the sign was 15 1/2 inches wide and 11 inches long, hence the area in square inches is given by:

[tex]A_{gr} = 11 \times 15.5 = 170.5[/tex]

For Gloria, the poster was 15.5 inches wide and 44 inches long, hence the area is of:

[tex]A_{gl} = 44 \times 15.5 = 682[/tex]

The ratio is given by:

[tex]r = \frac{A_{gl}}{A_{gr}} = \frac{682}{170.5} = 4[/tex]

The area of Gloria’s banner is 4 times larger than the area of Greg's sign.
