Solve the system by substitution.
3x-6y=2
4x+3y=-1

Answers

Answer:

y = -1/3

x = 0

Step-by-step explanation:

3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3

4x+3y = -1

substitute for x

4(2/3+2y)-6y = 2

8/3+8y-6y = 2

reduce

2y = 2-8/3

2y = -2/3

divide both sides by 2

y = -1/3

4x+3(-1/3) = -1

4x = 0

x = 0

2/5 of a number is -8 what is the number

Answers

Answer:

-20

Step-by-step explanation:

let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20

Answer: The number is 35

If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.

Step-by-step explanation:

Let the missing number = y

To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.

Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.

Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.

Thus,

2/5 of 14/y

2/5= 14/y

(2 x y) = (5 x 14)

(2y) = (70)

2y = 70

Since we are looking for value of y, divide both sides by the value beside y

Thus,

2y/2 = 70/2

y = 35

Therefore, the missing number is 35

For the given triangles ΔABC ≈ ΔXYZ, the length of side N is, 45/4

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

The triangle, ΔABC

Triangle ΔABC and ΔXYZ similar,

So, ΔABC ≈ ΔXYZ

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, AB/AC = XY/XZ

⇒ 5/8 = N/18

⇒ N = 45/4

Hence, the value of N is 45/4

Help me to find the value of x, please

Answers

Add all the values and set them equal to 180. This is because they make a straight angle. So...

15x + 90 + 8x-2 = 180
23x + 88 = 180
23x = 92
x = 4

Answer:

x = 4

Step-by-step explanation:

The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.

Also, every angle will add up to 360º, which is a crucial part of the equation

Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360

This can be simplified into this once you combine like terms:

46x + 176 = 360

Subtract 176 from 360, which will give you:

46x = 184

Divide by 46 on both sides, resulting in:

x = 4

To check the answer, plug in 4 for x:

15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360

60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360

120 + 180 + 60 = 360

360 = 360, x is 4

Which Type of account is used to store money for longer periods of time and is more likely pay interest to the account holder?O Checking AccountO Savings Account Hello I'm writing a book and I would like your opinion on it! This is just the beginning few pages.Gale! Is Gale here today students? I ran into class, the rain was pouring and I was drenched. Every speckle was so very small, delicate, and clear. I always admired the rain, to me it was a sign but I had not known of what. I sat down on my chair, as the floors got wet and I left a trail of water behind me. I did not realize that I had made the floors wet and that my jacket was cold and saturated. As I take my jacket off and put it in the cubbys that were placed by Arnold Peter, he gives me a gaze, then grabs me by the collar of my jacket that I had already taken half off and slams me to the floor.I looked up to see his face and then I met his eyes, they looked cold and pitiful. Gale! How dare you come to my class late and then pick a fight. You have the nerve. It was Mrs. Walter, she sent me to the principal's office and told me to see her during lunch to mop the wet floor. The principal threatened me with his offer of calling my parents, I didnt know what to say to him, so I just stood there blank. He then called me a disgrace and told me to be ashamed of myself.During lunch I sit alone and the other kids giggle away, I even hear them talk about me. I didnt have anything to eat and my parents didnt pay for my lunch. I guess I didnt mind starving, I was already used to these things and it has always been like this for the past 15 years of my life. I am interrupted from my daydreaming when Mrs. Walter takes me to her class and I start mopping the wet floor. She told me that I needed to fix my attitude and how my grades were suffering. It wasnt even my fault that the other kids liked to tease me. But then again, I was used to it. As the wet floors got dry, I noticed something.The water looked like it was shining, every speckle, glimmered. The lunch bell rings and I rush to my next class, I was hungry and wet from the morning rain so I didnt care much about the fascination the water brought to me. The last bell rings and I run home. The rain poured but I found comfort in it. I looked down at the bakery that was owned by Emma Walterson, my neighbor.She is a 45 year old woman who always cared about me and asked questions. Sometimes she even took me to her house and let me play in her sons consoles. I dont think he liked me that much. I dont look where I am going and get lost in my thoughts. Suddenly, the rain pours harder.Kids were running as their parents pulled up an umbrella. Some had friends that shared their umbrellas with them. Some didnt have one but they enjoyed the company they got from their friends. Then in a flash there was no one there. I guess they had all rushed home and I was just standing there.I started to run, faster and faster but it was like time had frozen. I look around to see the rain, it wasnt falling the trees in the distant were put, not moving. As I turn my head around trying to understand what was happening, the ground starts to shake. I tried pinching myself thinking I was having a bad dream. It wasnt a dream. Three oddly looking shapes appear in front of me. About 6 feet tall, rectangular and lustrous, it wasnt alive and it wasnt moving. It was an object and as I looked closer each of them had a symbol.The first symbol was a droplet of water. The second was a swirl, like the wind. And the third was a hand that held up a flower. I touch each symbol. The first symbol felt like real water as if I was standing there feeling water with my hands.The second symbol, the snowflake felt like it was ice which was no surprise. The third symbol, I couldnt feel. It was just the atmosphere. I then have a urge to fall into a slumber. I stumbled upon and lay down on to the ground. My long sky black hair fell in front of my eyes and my skin became pale. My bright blue eyes closed.That moment I was alone, tried, and starving. No one was there to help me, to carry me, to give me a hand, to lend a shoulder that I could lean on. I was alone, scared, and I didnt know where I was and what was happening to me. I wished for a new start to my so-called life. Three times the sum of a number, n, and 5 is at least 17.
