W-20.5=8 please help me

Answers

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

Any questions just ask me in the comments of this question :)

Calculate 48 x 3/8 choose the numbers to complete the equation

Answers

Answer:

1. Choose: 3

2. Choose: 144

3. Choose: 18

Step-by-step explanation:

The first thing you do is multiply 48 * 3/8= 18.  Then multiply 48 * 1/8= 6.  Then divide both answers to get 3, so 48 * 1/8 * 3.

Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).

Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

2.) D.) 2.38

Step-by-step explanation:

1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.

2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:

Start:         Year 1:     Year 2:      Year 3:      Year 4:

$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

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. Has anybody every completed online work that was dues last year? is that normal
