Answer:

she can't finish reading the book in 10 days

Step-by-step explanation:

Given that:

Number of pages = 325

Number of pages read per day= 25

Using the linear relation:

y = mx + c

y = number of pages left

m = reading rate ; c = initial number of pages

y = - 25x + 325

Point slope relation :

y - y1 = m(x - x1)

m = slope

We can factorise the equation to the point slope form:

y - 325 = 25(0 - 10)

y - 325 = 0 - 250

y - 325 = - 250

y = - 250 + 325

y = 75

Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days

Answer:

25

Step-by-step explanation:

5(x+6)−(5−x)−6x

Remember PEMDAS

P – Parentheses

E – Exponents

M – Multiplication

/D – Division  (whichever comes first from left to right)

A – Addition

/S – Subtraction (whichever comes first from left to right)

First, let's distribute the left side:

5 * x = 5x

5 * 6 = 30

5x + 30

Now, lets distribute the right side

-(5 - x) = -1(5 - x)

-1 * 5 = -5

-1 * -x = x  ( - * - = +)

x - 5

Now we have:

5x + 30 + x - 5 - 6x

Let's combine like terms.

5x, -6x, and x are like terms. 5x + x =  6x - 6x = 0

30 and -5 are like terms. 30 - 5 = 25

25

Since we can't simplify this any further, that is our answer.

Answer:

Step-by-step explanation:

4x - 9 = 35                   Add 9 to both sides

4x - 9 +9 = 35 + 9        Combine like terms

4x = 44                         Divide both sides by 4

4x/4 = 44/4                  Complete the division

x = 11

Answer:

11.2 hours

Step-by-step explanation:

The unknown is the hour time: 120+50.30x=250+38.70x. Now solve it: Subtract 38.70 and 120 from both sides and you get 11.6x=130 x=130/11.6 or 11.2 (about)

So the answer is 11.2 hours. Hope this helps :D

Answer:

So your answer is x = 11.2068965517

or

about, X = 11.21 (to the nearest tenth)

Step-by-step explanation:

50.30x + 120 = 38.70x + 250 (Given)

Move variables to the right and constants to the left by subtracting both sides.

11.6x = 130 (subtraction Property of equaity)

x = 11.2068965517 (Division property of equality)

Answer:

322 1/2 miles

Step-by-step explanation:

Recall how s = d/t ; speed = distance/time.

To effectively solve for distance traveled, rearrange the formula so that distance is on the left-hand side by multiplying speed, and time.

speed × time = distance/time × time

speed × time = distance

distance = speed × time ; d = st.

Now to find the total distance traveled, individually multiply the rate of speed with the time. Time will cancel, and we will get the total mileage.

Given an average speed of 60 mph at a certain time for 4.5 hours, and another average speed of 35 mph at another time of 1.5. Calculate the distance individually, and then add both distances together. Distance 1 = 60 mph × 4.5 h = 60 miles / h × 4.5h = 60 miles × 4.5 = 270 miles.

Distance 2 = 35mph × 1.5h = 35 miles / h × 1.5h = 35 miles × 1.5 = 52 1/2 miles.

Distance 1 + Distance 2 = Total distance.

270 miles + 52 1/2 miles = 322 1/2 miles.

Answer:

5

Step-by-step explanation:

Answer:

slope(m)=change in y/change in x

-7=y-(-2)/x-(-7)

-7=y+2/x+7

-7(x+7)=y+2

-7x-49=y+2

-7x-49-2=y

-7x-51=y (B)

The slope of a line is [tex]\frac{dy}{dx}[/tex]

where [tex]d[/tex] is the difference and [tex]y[/tex] and [tex]x[/tex] are the values.

In this case, the difference in [tex]y[/tex] is 10 and the difference in [tex]x[/tex] is 0

And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the [tex]y[/tex] axis.

AOBC is a parallelogram ,

Thus :

[tex]OA = BC = a[/tex]

And ;

[tex]AC = OB = b [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

M is the midpoint of AC ,

So :

[tex]AM = MC = \frac{b}{2} \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

According to case of Cosine in ∆ OAM :

[tex] {OM}^{2} = {OA}^{2} + {AM}^{2} - 2( OA) \times ( AM) \times \cos(A) \\ [/tex]

So :

[tex] {OM}^{2} = {a}^{2} + \frac{ {b}^{2} }{4} - 2(a)( \frac{b}{2} ) \cos(A) \\ [/tex]

[tex] {OM}^{2} = \frac{4 {a}^{2} + b}{4} - ab \cos(A) \\ [/tex]

Answer:

( [tex]\frac{5}{3}[/tex] , 0 ) ; ( 0 , - [tex]\frac{5}{2}[/tex] )

Step-by-step explanation:

- 3x + 2y = - 5

Coordinates of x-intercept are (x, 0)

- 3x + 2(0) = - 5 ⇒ x = [tex]\frac{5}{3}[/tex]

Coordinates of y-intercept are (0, y)

- 3(0) + 2y = - 5 ⇒ y = - [tex]\frac{5}{2}[/tex]

Answer:

27.7778

Step-by-step explanation:

If 13 out of 18 players are seniors then 5 of them are not.

To find the percentage you do (5/18) ⋅ 100

5 divided by 18 gives us 0.27777778

Then we multiply by 100 (or move the decimal point two spaces to the right)

The result should be 27.7778%

Step-by-step explanation:

same lenghts for sides, same measurements for angles and the orientation of the points is preserved

Answer:

[tex]\boxed {129\textdegree}[/tex]

Step-by-step explanation:

Both angles labeled, are actually Supplementary Angles (which two angles that add up to [tex]180\textdegree[/tex]). So, to find the missing measurement of an angle, which is the angle labeled in [tex]x[/tex], you need to take [tex]51\textdegree[/tex] and subtract it from [tex]180\textdegree[/tex] to get the missing angle measurement:

[tex]180\textdegree - 51\textdegree[/tex]

[tex]\boxed {129\textdegree}[/tex] (angle measurement for the angle labeled in [tex]x[/tex])
