Help. Find the sum of

-7x^2-6x+9 and -3x^2-x+7

[tex]\Large\boxed{\tt Answer: 5\frac{2}{3} }[/tex]

[tex]\tt Step-by-step~explanation:[/tex]

We can solve this by dividing both numbers by four.

[tex]\tt 8\div4=2\\12\div4=3\\\frac{2}{3}[/tex]

We then add that to 5 to get our answer.

Answer:

1,155 miles in a year.

Step-by-step explanation:

Assuming there are 4 weeks per month, that would mean there are a total of 48 weeks. If she takes 6 weeks off then that would leave 42 weeks. We know need to find how many minutes are in 11 hours by multiplying 11 by 60min.

11 * 60 = 660min

Now we need to divide 660min by the 24min it takes to walk 1 mile which will also give us the number of miles she walks per week

660 / 24 = 27.5 miles per week

Finally, we need to multiply the number of miles by the number of weeks in the year.

27.5 miles * 42 weeks = 1,155 miles in a year.

Answer:

21.53 in of fabric on headbands

7.67 in of fabric on wristbands.

Step-by-step explanation:

Step one:

given data

the total amount of person players plus coaches= 27+4= 31

for each person, she uses = 667.43/31= 21.53 in of fabric on headbands

She also uses 237.87inches of fabric on wristbands for just the players

For each player, she will use= 237.87/31= 7.67 in of fabric

Hence for each player, she used

21.53 in of fabric on headbands

7.67 in of fabric on wristbands

Answer:

-5

Step-by-step explanation:

slope is rise/run

so, the rise is -5, the 'run' is 1

so, -5

Answer:

0.22 miles/minute

Step-by-step explanation:

Tyler is riding his bike from his house to the store, which is 4 MI away. Tyler gets to the store it 18 minutes after he leaves his house.Find Tyler speed in miles per minute.

The formula for speed is given as:

Distance/Time

Hence:

Tyler's distance = 4 miles

Time = 18 minutes

Speed(Miles/ minute) = 4 miles/18 minutes

= 0.2222222222 miles per minutes

= 0.22 miles/minute

Answer:

B: y=35x

Step-by-step explanation:

You can verify this by plugging 1 to be x (35*1=35) and 2 (35*2=70)

Answer:

x = 6/7 of a puzzle

Step-by-step explanation:

Number of puzzle : time taken

= 3/4 : 7/8

How much a puzzle can she complete in an hour?

Let

x = number of puzzle to complete

Number of puzzle : time taken

= x : 1

Equate both ratios to solve for x

3/4 : 7/8 = x : 1

3/4 ÷ 7/8 = x / 1

3/4 × 8/7 = x / 1

24/28 = x / 1

Cross product

24 * 1 = 28 * x

24 = 28x

x = 24/28

= 6/7

x = 6/7 of a puzzle

Answer: 90%

Step-by-step explanation:

Answer:

90%

Step-by-step explanation:

In order to find the percentage of the money Juana spent while shopping, you must take the amount of money spent and divide it by the total amount of money.

$45 dollars spent divided by $50 dollars total will give you your fraction, in decimals:

45 / 50 = 0.90

Multiply by 100% to find your percentage

0.90 * 100% = 90.0%

Answer:

Step-by-step explanation:

4/7 x + 70 cm^3 = 3/4 x          Subtract 4/7 x from both sides

3/4 x - 4/7 x = 70 cm^3          The lowest common denominator is 28

[tex]\frac{3*7*x}{4*7} - \frac{4*4x}{4*7} = 70 cc\\\frac{21*x}{28} - \frac{16*x}{28} = 70 cc\\\frac{5x}{28}= 70cc\\[/tex]

5x = 70*28

5x = 1960                                Divide by 5

x = 1960/5

x = 392 cc

Answer:

Step-by-step explanation:

The difference of 3/4 and 4/7 of the volume is 70 cm:

5/28 of the volume is 70 cm³

Divide both numbers by 5/28 to find the total volume of the glass:

Answer:

Step-by-step explanation:

p=2.4×10^5.

q=3.7×10^5

pq = 2.4 * 10⁵ * 3.7 * 10⁵

    = 2.4 * 3.7 *10⁽⁵⁺⁵⁾

    = 8.88 * 10¹⁰

p + q = 2.4 * 10⁵ + 3.7 * 10⁵

      = ( 2.4 + 3.7) * 10⁵

      = 6.1 * 10⁵

[tex]y = \frac{pq}{p+q}\\\\ = \frac{8.88*10^{10}}{6.1*10^{5}}\\\\= 1.46 * 10^{10-5}\\= 1.46 * 10^{5}[/tex]

Answer:

113.3 pounds

5.17 ft

Step-by-step explanation:

Step one:

given data

weighs 1,360 ounces and is

Height = 62 inches tall.

Required:

We are expected to perform unit conversion

from ounces to pounds

and from inches to feet

Step two:

1 pound is 16 ounces

x pound is 1360 ounces

cross multiply

16x= 1360

x= 1360/16

x= 113.3 pounds

Step three

1 inches is 0.0833333ft

62 inches is x ft

cross multiply

x= 5.17 ft

Answer:

4x^5 - x^4 + 10xy^2.

Step-by-step explanation:

x^4 - 3xy^2 + P(x) = 4x^5 + 7xy^2

P(x) = 4x^5 + 7xy^2 -  (x^4 - 3xy^2)

= 4x^5 + 7xy^2 - x^4 + 3xy^2

= 4x^5 - x^4 + 10xy^2.

Answer:

[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]

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

[tex] = \frac{6}{3} = 2 [/tex]

Step-by-step explanation:

Find the slope (m) using the two points given, (-1, -5) and (2, 1):

[tex] slope (m) = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (-1, -5) = (x_1, y_1) [/tex]

[tex] (2, 1) = (x_2, y_2) [/tex]

Plug in the values into the equation:

[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]

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

[tex] = \frac{6}{3} = 2 [/tex]
