The expression that equals 2B + 2C in standard form of equation  is.

  [tex]4x^2 + 8x +16[/tex]

Calculations

2 (3x - 1) + 2 (2x^2 + x + 9)

6x - 2 + 4x^2 +2x + 18

[tex]4x^2 + 8x +16[/tex]

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y). When attempting to solve systems involving two linear equations, this form is also quite helpful.

Standard form refers to any number that may be expressed as a decimal number between 1.0 and 10.0 when multiplied by a power of 10.

The least number of pages Yao must read per hour to finish reading the book is 26 pages per hour. which is the correct answer would be an option (B)

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

Calculate the total number of hours Yao has left to finish reading the book by subtracting the number of hours he has already spent reading from the total number of hours he has available:

8 hours - 1 hour = 7 hours.

The number of pages Yao has left to read : 300 pages - 120 pages = 180 pages.

The number of pages Yao must read: 180 pages / 7 hours = 25.7 pages/hour.

Round up the number of pages Yao must read per hour to the nearest whole number. The least number of pages Yao must read per hour is 26 pages/hour.

Therefore, the minimum number of pages Yao must read each hour to finish the book is 26 pages per hour.

Answer:

[tex]\frac{49}{60}[/tex]

We can conclude that, both of them have eaten almost the complete bag of Tootsie rolls

Step-by-step explanation:

Given that:

Fraction of Tootsie rolls eaten by Jaxton = [tex]\frac{3}{5}[/tex]

Fraction of Tootsie rolls eaten by Drake = [tex]\frac{5}{12}[/tex]

Here, we have to use the Benchmark fractions to estimate what fraction of tootsie roll bags was eaten by Jaxton and Drake.

First of all, let us add the given two fractions to find the total amount of Tootsie rolls eaten by both of them together.

Total Tootsie rolls eaten by both of them =

[tex]\dfrac{3}{5} + \dfrac{5}{12}\\\\\text{Taking LCM of denominator i.e. 5 and 12 = 60}\\\Rightarrow \dfrac{3\times 12 + 5\times 5}{60}\\\Rightarrow \dfrac{49}{60}[/tex]

The most commonly used benchmark fractions are 0, [tex]\frac{1}{2}[/tex] and 1.

Here, with the fraction we can write our benchmark fractions as:

[tex]\dfrac{0}{60}, \dfrac{30}{60}, \dfrac{60}{60}[/tex]

We can see that, [tex]\frac{49}{60}[/tex] is near to [tex]\frac{60}{60}[/tex].

Therefore, we can conclude that, both of them have eaten almost the complete bag of Tootsie rolls.

Answer:

Step-by-step explanation:

slope is the diference in y over the difrevce in x

m= (y2-y1) / (x2-x1) = (5-2) / (0-1) = 3 / -1  = - (3/1)

Tip:

keep in mind that you can start with any point you want as long as you do the same order for x and y.

For example both of those are correct

m = (5-2) / (0-1) = 3 / -1  = - (3/1)

m = ( 2-5)/ (1-0) = -3/1 = -(3/1)

Answer:

78

Step-by-step explanation:

The difference is 30, which means that 4:9 is equal to 4x:9x, and the difference is 5x. x = 6, so 4x + 9x = 24 + 54 = 78

Answer:

j = [tex]\frac{2k+3}{5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5j-3}{2}[/tex] = k ( multiply both sides by 2 to clear the fraction )

5j - 3 = 2k ( add 3 to both sides )

5j = 2k + 3 ( divide both sides by 5 )

j = [tex]\frac{2k+3}{5}[/tex]

Answer:

$13.77 per person in the family

Step-by-step explanation:

Cost of the meal = $54.65

Sales tax rate = 8%

Sales tax amount = 8% of $54.65

= 8/100 × 54.65

= 0.08 × 54.65

= $4.372

Tip = 18% of $54.65

= 18/100 × 54.65

= 0.18 × 54.65

= $9.837

Total cost of the dinner = Cost of the meal + Sales tax amount + Tip

= $54.65 + $4.372 + $9.837

= $68.859

There are 5 people in the Holcombe family

What was the cost per person for the meal, including sales tax and tip?

cost per person for the meal, including sales tax and tip = Total cost of the dinner / total number of people in the family

= $68.859 / 5

= $13.7718

Approximately

$13.77 per person in the family

Step-by-step explanation:

The ratio of shots made to shots total is 7:15. Now since we don't know the shots made from 60 total shots, we can set the ratio as x:60. Since 15 goes into 60 4 times, we can multiply both parts of the ratio by 4 to get 28:60.

A. Sugar was central to people’s daily lives, work, and economy.

Step-by-step explanation:

Slavery was abolished in the British Empire in 1833, thirty years before the Emancipation Proclamation in the United States. But even after they freed their slaves, the sugar plantation owners were desperate to find cheap labor to cut cane and process sugar. So the British owners looked to another part of the empire—India—and recruited thousands of men and women, who were given five-year contracts and a passage back.

so that means

My great-grandparents had come from India to Guyana—then British Guiana—in the late nineteenth century to work on the sugar plantations. Sugar was the backbone of the British Empire at that time. The demand was huge, for sugar had gone from being a luxury that only kings could afford to a necessity. Even the poorest of London shopgirls took sugar in their tea.

Answer:

  150° CCW

Step-by-step explanation:

Apparently, we are to assume that segment A'B' is a reflection across line m, and that segment A"B" is another reflection across line p. Then the total angle of rotation is double the angle between lines m and p. The smaller angle is the supplement of 105°, so is 75°. Double that is 150°

The angle of rotation to get from A to A" is 150°.

__

The center of rotation is the point of intersection of p and m.

Answer:

D

Step-by-step explanation:

8 divided by 3 = 8/3

Answer:

The answer is below

Step-by-step explanation:

a)

1/4x + 5/2x - 2 = 4 - 1/4x

collecting like terms:

(1/4)x + (5/2)x + (1/4)x = 4 + 2

3x = 6

x = 6/3

x = 2

b)

7.9x + x + 4 = -1.1x - 16

collecting like terms:

7.9x + x + 1.1x  = - 16 - 4

10x = -20

x = -2

c)

3.2x + 5.7 = -2.5x

collecting like terms:

3.2x + 2.5x = 5.7

5.7x = 5.7

x = 1

d)

10.1x - 1.6x + 44 = -7

collecting like terms:

10.1x - 1.6x = -7 - 44

8.5x = -51

x = -6

Hence the equations in increasing order of the value of their solutions is:

10.1x - 1.6x + 44 = -7

7.9x + x + 4 = -1.1x - 16

3.2x + 5.7 = -2.5x

1/4x + 5/2x - 2 = 4 - 1/4x
