What is the value of the expression (x+y) + 5 if x = 6 and y =4


Answers

Answer:

15

Step-by-step explanation:

the expression is (x+y)+5

Now, you need to plug in x=6 and y=4.

So, you have the expression, (6+4)+5

You then add the 6 and 4 since they are in parenthesis, which equals 10. Then you add the 5, which equals 15.

Solve for x enter the solution from least to greatest x2 - 11x + 18 =0

Answers

Answer:

x = 2 , 9

Step-by-step explanation:

[tex] {x}^{2} - 11x + 18 = 0[/tex]

[tex] = > {x}^{2} - 9x - 2x + 18 = 0[/tex]

[tex] = > x(x - 9) - 2(x - 9) = 0[/tex]

A store sells shirts at a price of 2 for $5.00. At this price, how much do 7 shirts cost?

Answers

Answer:

$17.50

Step-by-step explanation:

2 goes into 7 3 times, and 5 times 3 is $15.00, so theres one shirt left. If 2 shirts cost $5, one will cost $2.50. So, 15+2.50= $17.50

5/2 equals 2.50 so 2.50x7 equals 17.50

Step-by-step explanation:

Jalen had read 14 chapters out of the book .. if this is 56% of the chapters, how many chapters are in the book?

Answers

Answer:

25 Chapters

Step-by-step explanation:

We are given:

Number of Chapters read = 14

Percentage of Book finished = 56%

Number of Chapters in the Book:

Since 56% of 'x' chapters is 14:

[tex]x*\frac{56}{100}[/tex] = 14

[tex]x = \frac{14 * 100}{56}[/tex]                             [multiplying both sides by 100/56]

[tex]x = \frac{100}{4}[/tex]                                  [since 14*4 = 56]

x = 25

Therefore, the book has 25 chapters

Answer:

The book has a total of 25 chapters.

Step-by-step explanation:

We are given that Jalen has read 14 chapters of his book. We are also given that 14 chapters is 56% of the entire book. We need to find how many chapters are in the book.

If 14 is 56% of the book, we can set up a proportion that can find the total number of chapters in the book.

A proportion looks like:

[tex]\displaystyle \frac{a}{b} = \frac{c}{d}[/tex]

Our first fraction will be the two values we are given: 14 chapters and 56% of the book.

[tex]\displaystyle \frac{14}{56}[/tex]

Then, our second fraction will contain an unknown variable. We would need to complete this many chapters to complete the book, so 100% of the book would be read once a certain number of chapters are reached. Therefore, we don't know how many chapters are needed to complete the book, so this is our unknown variable. We can define this as x.

Therefore, our second fraction is:

[tex]\displaystyle \frac{x}{100}[/tex]

Now, we can set these fractions equal to each other.

[tex]\displaystyle \frac{14}{56} = \frac{x}{100}[/tex]

Then, we can cross multiply our fractions to create an equation. Following our sample proportion, we would get:

[tex]{ac = bd}[/tex]

So, we can follow the same policy with our proportion.

[tex]\displaystyle (14)(100) = (56)(x)\\\\1400 = 56x\\\\56x = 1400\\\\\frac{56x}{56} = \frac{1400}{56}\\\\x = 25[/tex]

Therefore, 56% of the book is 14 chapters. With this information, we have determined that 100% of the book is 25 chapters.

Snow Dome Ski Resort has 75 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resort has 68 inches of snow. Currently it is snowing there at a rate of 2 inches per hour.

a) Make a table or a graph showing the amount of snow from 0 to 10 hours at each resort if the snow continues falling at this rate.

b) Indicate on your table or graph where the amount of snow will be the same at both resorts.

Answers

Answer:

a. See explanation for table

b. The 7th hour

Step-by-step explanation:

Given

Ski Resort

[tex]Base\ Snow = 75in[/tex]

[tex]Rate = 1in[/tex] hourly

Mt. Winterpark

[tex]Base\ Snow = 68in[/tex]

[tex]Rate = 2in[/tex] hourly

First, we need to illustrate the amount of snow as an equation in both cases.

[tex]Amount = Base\ Snow + Rate * Time[/tex]

Let x be number of hours. and y be the amount of snow

So:

Ski Resort

[tex]y= 75 + 1* x[/tex]

[tex]y= 75 + x[/tex]

Mt. Winterpark

[tex]y= 68 + 2 * x[/tex]

[tex]y= 68 + 2x[/tex]

Next, we make a table to show the data.

When [tex]x = 0[/tex]

Ski Resort: [tex]y = 75 + 0 = 75[/tex]

Mt. Winterpark: [tex]y = 68 + 2(0) = 68[/tex]

When [tex]x = 1[/tex]

Ski Resort: [tex]y = 75 + 1 = 76[/tex]

Mt. Winterpark: [tex]y = 68 + 2(1) = 70[/tex]

When [tex]x = 2[/tex]

Ski Resort: [tex]y = 75 + 2 = 77[/tex]

Mt. Winterpark: [tex]y = 68 + 2(2) = 72[/tex]

When [tex]x = 3[/tex]

Ski Resort: [tex]y = 75 + 3 = 78[/tex]

Mt. Winterpark: [tex]y = 68 + 2(3) = 74[/tex]

When [tex]x = 4[/tex]

Ski Resort: [tex]y = 75 + 4 = 79[/tex]

Mt. Winterpark: [tex]y = 68 + 2(4) = 76[/tex]

When [tex]x = 5[/tex]

Ski Resort: [tex]y = 75 + 5 = 80[/tex]

Mt. Winterpark: [tex]y = 68 + 2(5) = 78[/tex]

When [tex]x = 6[/tex]

Ski Resort: [tex]y = 75 + 6 = 81[/tex]

Mt. Winterpark: [tex]y = 68 + 2(6) = 80[/tex]

When [tex]x = 7[/tex]

Ski Resort: [tex]y = 75 + 7 = 82[/tex]

Mt. Winterpark: [tex]y = 68 + 2(7) = 82[/tex]

When [tex]x = 8[/tex]

Ski Resort: [tex]y = 75 + 8 = 83[/tex]

Mt. Winterpark: [tex]y = 68 + 2(8) = 84[/tex]

When [tex]x = 9[/tex]

Ski Resort: [tex]y = 75 + 9 = 84[/tex]

Mt. Winterpark: [tex]y = 68 + 2(9) = 86[/tex]

When [tex]x = 10[/tex]

Ski Resort: [tex]y = 75 + 10 = 85[/tex]

Mt. Winterpark: [tex]y = 68 + 2(10) = 88[/tex]

Hence, the table is:

x ---- Ski Resort ---- Mt. Winterpark

0 --------75 ----------- 68

1 --------76 ----------- 70

2 --------77 ----------- 72

3 --------78 ----------- 74

4 --------79 ----------- 76

5 --------80 ----------- 78

6 --------81 ----------- 80

7 --------82 ----------- 82

8 --------83 ----------- 84

9 --------84 ----------- 86

10 -------85 ----------- 88

(b)

From the table, the amount of snow is the same at the 7th hour and the snow is 82 inches
