A book sold 35,300 copies in its first month of release. Suppose this represents 6.3 of the numbers sold to date. How many copie

skelet666 [1.2K]

Answer:

560,317.460

Step-by-step explanation:

The computation of copies that have been sold is shown below:-

we assume the number of copies is x

So, the number of copies in the first month is

= $\frac{6.3}{100} x$

As per the situation the number of sold copies is 35,300 so the equation will be

$\frac{6.3}{100} x = 35,300$

$6.3x = 35,300\times 100$

$x = \frac{35,300\times 100}{6.3}$

after solving the above equation we will get the number of copied that have been sold to date

= 560,317.460

Find b, if a is (5, -3) and m (-4, 2) is the midpoint of ab

Dennis_Churaev [7]

We were given the points, A(5,-3) and the midpoint of AB, M(-4,2).

Let point B have coordinates (c , d).

Then the midpoint of A(5, -3) and B(c,d)

$= ( \frac{5 + c}{2} \: \: \: \frac{ - 3 + d}{2} )$
Now let us compare to the given midpoint M(-4, 2).

We can then write the following equations for the corresponding coordinates.

Comparing x coordinates, we have;

$\frac{ 5 + c}{2} = - 4$
Multiplying both sides of the equation by 2 gives,

5+c = 2(-4)

Simplifying the right hand side gives,

5 + c = -8

Grouping like terms, we have,

c = -8 - 5

This simplifies to,
c = -13

Comparing y coordinates we have,

$\frac{ - 3 + d}{2} = 2$
Multiplying through by 2 gives,

-3 + d = 2(2)

This means that,

-3 + d = 4

Making the subject we have,

d = 4+3

This implies that,

d = 7

Hence the coordinates of B are (-13,7).
