8x2 - 6x + 3 – 2x – 10x?

Answers

Answer 1

Answer:

8[tex]x^{2}[/tex] + 3 + -6x

Step-by-step explanation:

First we need to find the like terms so that we could add them. In this case the like terms are,

1. 6x , -2x , -10x

So, these are the only terms that we can add in this expression.

Hence,

=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)

=> 8[tex]x^{2}[/tex] + 3 + -6x

And this is as simple as this expression can go until we find the value of "x" which is not yet told.

Hope my answer helped.

Carmine pain an electrician x dollars per hour for a 5 hour job plus 70 for parts. The total charge was 320 which equation can be used to determine how much do electrician charge per hour

Answers

Answer:

5x + 70 = 320

Step-by-step explanation:

We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.

He also got paid 70 for parts, meaning an extra $70

And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.

Therefore :

5x + 70 = 320

Step-by-step explanation:

In similar triangles, the sides keep the same ratio, in this case 3:4:5.

Thus, because 12 is 3*4 and 20 is 5*4, x must be 4*4, or 16.

Step-by-step explanation:

When rounding to the nearest whole number by looking at the tenth's value. Remember if it is 5 or more you would raise the number while if it is 4 or less you would round down. In your case you would round down.

0.5, 0.6, 0.7, 0.8, 0.9=1 if rounded to nearest whole number.

0.1, 0.2, 0.3, 0.4=0 if rounded to nearest whole number.

A large hose can fill 7/8 of a water tank in one hour. A small hose can fill 3/4 of a water tank in one hour. How much more of a water
tank can the large hose fill in one hour than the small hose?
can fill

Answers

Answer:

The large hose can fill 1/8 more of the tank in on hour than the small hose

Step-by-step explanation:

To understand this, we need to make 7/8 and 3/4 have the same denominator

3/4 and 6/8 are the same in decimal form (0.75)

So we change 3/4 to 6/8

So now we subtract what the small hose fills per hour from what the large hose fills per hour

7/8 - 6/8 = 1/8

So the large hose fills 1/8 more of the tank per hour than the small hose

What is y = mx + b mean for functions

Answers

Answer:

Slope-Intercept Form. A function whose graph is a line or a part of a line is called a linear function. In general, a linear function is a function that can be represented by an equation in the form y = mx + b. The form y = mx + b, or f(x) = mx + b, is called the slope-intercept form of a linear equation

Step-by-step explanation:

hope this help:))

the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 34 ft long, what is its volume?

Answers

Given:

The diameter of the cylindrical pipe = 6ft.

Height of the pipe = 34 ft

To find:

The volume of the pipe.

Solution:

We have,

Diameter of cylinder = 6 ft

Radius of cylinder [tex]=\dfrac{6}{2}=3[/tex] ft

Height of the pipe = 34 ft

Volume of a cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting r=3 and h=34, we get

[tex]V=\pi (3)^2(34)[/tex]

[tex]V=\pi (9)(34)[/tex]

[tex]V=306\pi [/tex]

[tex]V=306(3.14)[/tex]

[tex]V=960.84[/tex]

Therefore, the volume of the cylindrical pipe is [tex]306\pi \approx 960.84[/tex] cubic ft.

Brandon went to the store and spent $2.50 on pencils. He spend half of what he had left on a notebook and paper. When he got home he had $5.00 left. How much money did Brandon have before going to the store?

A) make a table, chart or list
B) work backwards
C) use a formula
D) look for a pattern

Answers

Answer:

B) work backwards.

Step-by-step explanation:

Since they are asking for how much money he had at first and they displayed how much he spent without telling the amount of money at the start of the question, this is definitely a backwards question. For working backwards, you will need to do workings the opposite as what they said in the question.

Hello I'm writing a story and I would like your opinion on it!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 skyy 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. What change in society after World War I increased the role and influence of both the NAACP and the Ku Klux Klan during the 1920s?
