Jori has 7 boxes of books,with each box holding the same number of books.he has126 books in all how many books are there per box
bazaltina [42]
Let b be the number of books in a box.  Then we can say that the total number of books is equal to the number of boxes times the number of books per box.

7b=126  divide both sides by 7

b=18

So there are 18 books per box.

The length and width of a rectangle are shown below.
natulia [17]

Answer:

-2x² + 90x + 500

Step-by-step explanation:

Use FOIL method

Area of rectangle = length * width

                             = (50 - x)(2x + 10)

                             = 50*(2x) + 50*10 + (-x)*2x + (-x)*10

                             = 100x + 500 - 2x² - 10x

                             = -2x² + 10<u>0x - 10x </u>+ 500  {Combine like terms}

                            = -2x² + 90x + 500

Simplify the midpoint of QS.
oee [108]

Answer:

[(a + b), c]

Step-by-step explanation:

Midpoint of a segment with extreme ends represented by ordered pairs (x_1,y_1) and (x_2,y_2),

Midpoint = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

It is given that extreme ends of the segment QS are Q(2b, 2c) and S(2a, 0)

Coordinates of the midpoint of QS will be,

= (\frac{2a+2b}{2},\frac{2c+0}{2} )

= [(a + b), c]

Therefore, ordered pair representing the midpoint of QS will be [(a + b), c].

Write an equation that can be used to solve the problem. Then answer the question asked. A group of college students are volunte
svp [43]

Answer:

Required equation : \frac{1}{t}=\frac{1}{3}+\frac{1}{9}

Together they can paint the same room in 2.25 hours or 2 hours 15 minutes.

Step-by-step explanation:

It is given that Dale Horton can paint a certain room in 3 hours.

One hour woks of Dale Horton = 1/3

Kathy Garcia can paint the same room in 9 hours.

One hour woks of Kathy Garcia = 1/9

Let together they can paint the same room in t hours.

One hour woks of both = 1/t

\frac{1}{t}=\frac{1}{3}+\frac{1}{9}

\frac{1}{t}=\frac{3+1}{9}

\frac{1}{t}=\frac{4}{9}

After reciprocal we get

\frac{t}{1}=\frac{9}{4}

t=2.25

1 hour = 60 minutes.

0.25 hour = 15 minutes.

Therefore, together they can paint the same room in 2.25 hours or 2 hours 15 minutes.
