Answer:

x = 0.327

Step-by-step explanation:

$\frac{21}{4}$ = $\frac{12}{7}$ ÷ <em>x</em>

$\frac{21}{4}$ = $\frac{12}{7}$ × $\frac{1}{x}$

$\frac{21}{4}$ = $\frac{12}{7x}$

$\frac{21}{4}$ x 7x = 12

$\frac{147x}{4}$ = 12

147x = 12 x 4

x = 48 ÷ 147

x = 0.327

21/4=12\7:x

21 se simplifică cu 7 și o să ne dea 3

și 1

12 se simplifică cu 4 și o să ne dea

3 și 1

3\1=3\1:x

x=3x3

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth

bija089 [108]

Answer:

<h2>The answer is 13.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (10,-1) and B (-2,5)

The distance is

$|AB| = \sqrt{ ({10 + 2})^{2} + ({ - 1 - 5})^{2} } \\ = \sqrt{ {12}^{2} + ({ - 6})^{2} } \\ = \sqrt{144 + 36} \: \: \: \: \: \: \: \\ = \sqrt{180} \\ = 6 \sqrt{5} \: \: \\ =13.416407$

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>
