The library question please, and can u please explain, I’ll give many points

Answer: 1,260 books are due back this week.

Step-by-step explanation:

So, 12500/5 = 2500

2500 * 2 = 5000

5000 is 2/5 out of 12,500

19000/5 = 3800

3800 * 2 = 7600

7600 is 2/5 out of 19000.

7600 + 5000 = 12,600

12600 total books are checked out.

12600/10 = 1260

1260 * 1 = 1260

The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x represents the small

Marta_Voda [28]

For this case we have the following equation:
$x (x + 1) = 72
$
We can rewrite the expression.
For this, we first make distributive property:
$x ^ 2 + x = 72
$
Then, we add -72 on both sides of the equation:
$x ^ 2 + x - 72 = 72 - 72
$
Rewriting we have:
$x ^ 2 + x - 72 = 0
$
This is the equation that must be factored and solved for the smallest integer.
Answer:
An equation that can be factored and solved for the smaller integer is:
$x ^ 2 + x - 72 = 0$

Find the midpoint of the segment with the following endpoints (4,5) and (1,2)

olga55 [171]

Answer:

Step-by-step explanation:

Mid point of two points is given as

Let Point 1 be(x1,y1)

And point 2 be (x2,y2)

Then, mid point is given as

M = [ (x1+x2) / 2 , (y1+y2) / 2 ]

So, given that,

Point 1 =(4,5)

Then, x1=4 and y1=5

Point 2=(1,2)

Also, x2=1 and y2=2

Then, applying the formulae

M = [ (x1+x2) / 2 , (y1+y2) / 2 ]

M = [ (4+1) / 2 , (2+5) / 2 ]

M = [ 5 / 2 , 7 / 2 ]

Then, the midpoint is

M=(5/2, 7/2)

To decimal point

M=(2.5 , 3.5)

To mixed fraction

M=(2½, 3½)

(x, y)=(2½, 3½)
