How to solve this? Please someone help

Answers

Answer:

Step-by-step explanation:

So the sign means that y has to be less than or equal to x plus 9

if you wanted an answer an example could be

y = 1

x = 10

this works because if implemented into the equation

1 ≤ 10 + 9 which is true

If you’re solving for x. It’s
x ≥ y −9

Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve

Answers

Answer:

15 equations

Step-by-step explanation:

Let

Number of equations in the homework = x

There is only a one-word problem

y = amount of time used to solve the word problem

She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,

Total = 3x + y

52 = 3x + 7

Subtract 7 from both sides

52 - 7 = 3x + 7 - 7

45 = 3x

Divide both sides by 3

x = 45 / 3

= 15

x = 15 equations

Therefore, she solved 15 equations

Bulk sugar is on special at $0.97 per kilogram. Betty scooped some on a scale. How much will she pay for 5,068 grams of sugar?

Answers

Answer:

There are 1000 grams in a kilogram. 5068g is therefore 5.068kg so the cost to Betty is 5.068 * .97 = $4.92

The price to pay for 5,068 grams of sugar will be $4.91.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Bulk sugar price = $0.97 per kilogram.

Now,

Since, 1 gram = 1/1000 kilograms

So, 5,068 grams = 5,068 / 1000

= 5.068 kilograms

Here, The price of 1 kilogram Bulk sugar = $0.97

Hence, The price of 5.068 kilogram Bulk sugar = 5.068 x $0.97

= $4.91

Thus, The price to pay for 5,068 grams of sugar will be $4.91.

Please list two additional interesting facts about the Stylophone:[I I'm not good at determining what is happening in a volleyball game. So if you can understand what I'm describing in this essay, the information I'm saying is relevant, and you actually understand how volleyball works, can you please tell me if this is good? Any negative comments are helpful.The team's playing in this video are presented as Baylor Bears and Texas Longhorns. Baylor is #3 with a win to loss ratio of 11-2 for this season while Taylor is #1 with their unbeaten 11-0. Texas hit 294 as a team while Baylor hit 233, Texas Longhorns so far is the best hitting team efficiency wise in the country with a score of .359. Baylor took the lead in the first two sets when they made their first o2 comeback ever since Nov 1st of 2017. Hannah Sedwick, #14 Setter, in Baylor to me, seems like a really focused player, they mentioned how she was out for most of the season due to a fracture in her leg but yet she seems so active and awake, all of the players put in an effort but Hannah actually commits. When blocking the ball, her entire body became stiff and she carried the win for her team. On the other team there's Yossiana Pressley, #32 Outside Hitter, on the Baylor Bears who had 29 kills in the first part, and I have to say she completely dominated Baylor's with her spikes. Nilani Iosia, #12 Libero, in the Texas Longhorn scored 15 digs and an excellent passing percentage while Lauren Harrison, #31 Outside Hitter, Baylor Bears was the second leading attacker in the first part. Another notable player is Jhenna Gabriel, #2 setter, in Texas Longhorns who is the reigning national player of the big 12 player of the year.The Texas Longhorns came through this game with a ratio of 3-2 remaining unbeaten for the 12th time in a row. In one play I remember Butler barely hit the ball over the net and scored. It wasn't such a critical play but it had strategy and reasoning behind it. While Baylor prepared for the worst by upgrading the offense, they left their defense bare. That's why I think it was smart how Butler quickly noticed that and surprised them. This team had a quick dynamic where they would hit the ball before the blockers could completely cover over the net. Somewhere in the beginning, I immediately had a feeling Taylors had something the Bears didnt which helped them stay unbeaten. Id say its how they made sure to make their hits clear so that it can go through the blockers, and they were very efficient with passing the ball to their hitters. They shouldve had a clearer touch with the ball as well even if they won, it looked like both teams couldnt block the ball most of the time.The losing team, Baylor Bears, was honestly close to Texas's score. I couldn't stop focusing on Yossiana Pressley in Baylor, she had perfect momentum and sharp reflexes. Not just because of her kills but I'd say she was the MVP player of this game. The team was always so supportive as well especially whenever a small mistake occurred like a foul for going over the line on a serve. I have to admit, most of their sets were average, and not to mention how their hitters would constantly hit out of the court. It seemed as if they were trying to get it to hit the net so Taylor's would have more difficulty blocking it, if that's the case then it's a very smart move, but otherwise, if they just happened to be lucky then I'd consider it a miracle. This team could always track the ball but when it came to controlling the ball, they were late and had bad momentum. The sad part is, the Baylor Bears are such a good team, I personally liked them more in the beginning where I saw more action, but whenever it came down to the ball constantly being passed back and forth it seemed as if they lost energy which to me, ultimately led to the downfall of their team.

Read the passage. First identify the text structure used in the passage, and then explain how this structure helps develop the writer's central idea. Use evidence from the text in your response.The rise in popularity of farmers' markets has caused many people to rethink their use of regular grocery stores. Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!!
