Answer:

Hey there !

Solution:

Let the number be x

=> x + 2x² = 10

=> 2x² + x - 10 = 0

Factorising the quadratic equation we get,

=> 2x² + 5x - 4x - 10 = 0

=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0

=> ( x - 2 ) ( 2x + 5 ) = 0

=> x = 2, -5/2

Since x is a whole number, -5 / 2 wont be applicable.

Hence x = 2.

Hence the number is 2.

Hope my answer helped !

Complete question :

On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.

Answer:

1.497 * 10^8km

149700000 km

Step-by-step explanation:

Given that:

Time taken = 8 minutes 19 seconds

Speed of light = 3 * 10^8 m/s

Distance from earth to sun :

Speed * time

(3 * 10^8) * ((8 * 60) + 19)

(3 * 10^8) * 499

= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km

= 149700000000 m

= 149700000 km

= 1497

Answer:

Shirt: $2.25. and Pants: $1.50

Step-by-step explanation:

Set up equations with shirts as s and pants as p.

Subtract them as there are two variables and two equations:

To find s:

Answer:

(y - 25) = - 0.25(x - 20)

Step-by-step explanation:

Given that :

Height of candle after burning for 20 minutes = 25 cm

Height after burning for 1 hr (60 minutes) = 10 cm

Height (y) in cm of candle x minutes after being lit:

Using the equation :

(y - y1) = m(x - x1)

m = (change in y / change in x)

Change in height within 60 minutes :

Height at 20 minutes = 25cm

Height after an hour = 10

Change in height per hour = (25 - 10) = 15cm

Hence, m = change in height per minute

15cm / 60 = 0.25cm ( - 0.25) (decrease in height)

y1 = 25 ; x1 = 20

(y - y1) = m(x - x1)

(y - 25) = - 0.25(x - 20)

Answer:

Step-by-step explanation:

y=3/4x-2

Answer:

y=3/4x-2

Step-by-step explanation:

slope-intercept formual: y = mx + b

m (the slope) = (y2-y1) / (x2-x1) so right here we insert (4-1) / (8-4) = 3/4  

b =w here the line touches the y-asix = -2

now insert those numbers in the formual: y = (3/4)x + (-2)

final answer: y=3/4x-2

Answer:

Answer: C. (1,1)

Step-by-step explanation:

Midpoint

Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The endpoints are (-2,-4) and (4,6).

Calculating the midpoint:

[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]

[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]

The midpoint is (1,1).

Answer: C. (1,1)

Answer:

(-3a+4b) (2x+2y)

Step-by-step explanation:

Expand.

4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)

4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)  = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay

Calculate like terms.

12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by

Factorise.

-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)

Factorise further.

-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)

Step-by-step explanation:

Answer:

The value of each book is 7  

The value of each music note is 6

Step-by-step explanation:

The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.

The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.

This is the system that represents the puzzle:

3b + 2m = 33

b + 3m = 25  

Solve the second equation for b, and then substitute the equivalent expression for b in the first equation.  The value of each music note is 6.

Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

Step-by-step explanation:

2n is the answer because you combined the two variables then you do 20n plus 20n minus. 10 equals 50 then subtract 10 from 50 and get forty the divide that by 20 which equals 2

Answer:

$35.75 per hour

Step-by-step explanation:

In order to calculate this, we first need to calculate how much she made with her current hourly wage. We do this by multiplying the hours she worked by her current hourly wage plus her raise.

32 hours * (40+2) = $1,344

Now we subtract $200, since this is how much more she is making with her raise, and then we divide that amount by the 32 hours she is working per week.

(1,344 - 200) / 32 = $35.75 per hour

Finally, we can see that Vanessa's hourly wage before the raise was $35.75 per hour
