Answer:

Answer in simplified form is - 10 1/2 .

Step-by-step explanation:

We have given,

(5 1/4) ÷ (- 2 1/2)

This can be simplified as :

(5 1/4) ÷ ( -2 1/2)

Since 5 1/4 = 21/4 and -2 1/ 2 = -5/2

So we can write,

(5 1/4) ÷ ( -2 1/2) = 21/4 ÷ ( - 5/2)

or (21/4) / (-5/2)

or ( 21/4) * (-2/5)

or -42/20

or -21/10

or - 10 1/2 , this is the answer

Hence we get answer in simplified form as -10 1/2

What is the slope formula of (4,2) and (7, 6.5)

Lady_Fox [76]

Suppose the given coordinates are represented as,

$\begin{gathered} (x_1,y_1)=(4,2) \\ (x_2,y_2)=(7,6.5) \end{gathered}$

Then, the formula for slope can be expressed as,

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{6.5-2}{7-4} \end{gathered}$

Solving it,

$m=\frac{4.5}{3}=1.5$

The slope is 1.5.

The formula of (10, 8) anjd (-5,8) is

Segment AB with endpoints at A(2, 4) and B(2, 18) is partitioned by point P according to the ratio of 3:4. Find the coordinate o

natta225 [31]

Using proportions, it is found that the coordinates of point P are given as follows: (2,10).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The segment is partitioned by point P according to the ratio of 3:4, hence:

$P - A = \frac{3}{7}(B - A)$

This proportion is applied for both coordinates, hence, for the x-coordinate:

$x - 2 = \frac{3}{7}(2 - 2)$

x - 2 = 0

x = 2.

For the y-coordinate:

$y - 4 = \frac{3}{7}(18 - 4)$

y - 4 = 6

y = 10.

Hence the coordinates are (2,10).
