Answer:

Co-efficient of [tex]x^{2}[/tex] is missing.

It should be 8[tex]x^{2}[/tex].

Step-by-step explanation:

Given two polynomials:

1st polynomial: [tex]15x^2+11y^2+8x[/tex]

2nd polynomial: [tex]-7x^2+5y^2+2x[/tex]

To find:

The value in the blank:

[tex](15x^2+11y^2+8x)-(7x^2+5y^2+2x)= \_\_ \ x^2+6y^2+6x[/tex]

Solution:

Here, we have 3 pair of like terms.

2 terms with [tex]x^{2}[/tex], 2 terms with [tex]y^{2}[/tex]and 2 terms with [tex]x[/tex].

Like terms can be subtracted.

Subtracting the terms with [tex]y^{2}[/tex], the coefficients will get subtracted.

[tex]11y^2 - 5y^2 = 6y^2[/tex]

Subtracting the terms with [tex]x[/tex], the coefficients will get subtracted.

[tex]8x -2x=6x[/tex]

Subtracting the terms with [tex]x^{2}[/tex], the coefficients will get subtracted.

[tex]15x^2 - 7x^2 =\bold{8}x^2[/tex]

Therefore, the answer is:

Co-efficient of [tex]x^{2}[/tex] is missing.

It should be 8[tex]x^{2}[/tex].

Answer:

previously repaved= 6,609cm

Step-by-step explanation:

Giving the following information:

So far, they have repaved a total of 8,747 centimeters of the road. Today, they repaved 2,138 centimeters of the road.

To calculate the number of centimeters repaved, we need to use the following formula:

Total centimeters= repaved today + previously repaved

8,747= 2,138 + previously repaved

6,609=previously repaved

Answer:

[tex]y=\frac{-1}{2}x +\frac{5}{2}[/tex]

Step-by-step explanation:

Slope intercept form looks like y=mx+b

The slope (m) needs to be the opposite reciprocal of 2, because the line needs to be perpendicular the given line. Therefore, m = -1/2

We can write the equation in point-slope form first because we're given a point and now we have the slope. The equation would be [tex]y-0=\frac{-1}{2} (x-5)[/tex]

Rewriting, we get [tex]y=\frac{-1}{2}x +\frac{5}{2}[/tex]

x<5

Step-by-step explanation:

Answer:

x<5

Step-by-step explanation:

First, subtract 10 from both sides which will give you −5x>−25.

Then just divide both sides by -5 and you should get the same answer x<5

Answer:

here are 3 times as many boys as girls in a room. If 4 boys and four girls leave the room, then there will be 5 times as many boys as girls in the room. In total, how many boys and girls were in the room originally?

8 girls

24 boys

There were 24 boys and 8 girls in the room originally.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Given that there are 3 times as many boys as girls in a room.

If 4 boys and 4 girls leave the room, then there will be 5 times as many boys as girls in the room.

Let's assume the number of boys would be b

And the number of girls would be g

According to the given condition, the required solution would be as:

b = 3g               ....(i)

b - 4 = 5 (g - 4) ....(ii)

Substitute the value of b = 3g in equation (ii), and solve for g

3g - 4 = 5 (g - 4)

3g - 4 = 5g - 20

5g - 3g = 20 - 4

2g = 16

g = 8

Substitute the value of g = 8 in equation (i), and solve for b

b = 3 × 8

b = 24

Hence, there are 24 boys and 8 girls in the room.

Answer:

$50

Step-by-step explanation:

Change 250 to a decimal:

250/100 = 2.50

multiple the price by this decimal to find the new price:

$20 x 2.50 = $50

The distance between a boat and a cliff is 129 feet.

The trigonometric functions are used to determine the distance and angle in real-life situations.

Consider the following diagram.

Let the distance between a boat and a cliff be [tex]x[/tex].

[tex]tan25^{o}=\frac{40}{x}[/tex]

[tex]x=\frac{35+25}{tan25}[/tex]

[tex]x=\frac{60}{0.4663}[/tex]

[tex]x=128.67[/tex]

Therefore, the distance between a boat and a cliff is 129 feet.

Answer:

  $400

Step-by-step explanation:

If the price after taking 25% off is $300, then $300 is 75% of the original price.

  $300 = 0.75p

  $300/0.75 = p = $400

The original price was $400.

_____

Check

0.25 × $400 = $100

$400 -100 = $300 . . . . the price after taking 25% off
