Answer:

c = 2 or c = -3/10

Step-by-step explanation:

23. 10c2 - 21c = -4c + 6

10*cc - 21c = -4c + 6

10cc - 21c + 4c - 6 = 0

10cc - 17c - 6 = 0

c = 17/20 + root (17*17 - 4*10 *(-6)) / 20

c = 17/20 + 23/20

c = 2 or c = -6/20 = -3/10

Find the value of x.

Alik [6]

Answer:

$x =15$

Step-by-step explanation:

In $\odot D,$ AB and AC are chords which are equidistant from the center of the circle.

$\therefore Chord \: AB \cong Chord\: AC$

$\therefore m \widehat {AB} = m\widehat {AC}$

(Equal chords intercept equal arcs)

$\because m \widehat {AB} = (10x-23)\degree$

$\therefore m \widehat {AC} = (10x-23)\degree$

$m \widehat {AB} +m \widehat {AC} +106\degree = 360\degree$

(Arc sum postulate of a circle)

$(10x-23)\degree + (10x-23)\degree= 360\degree- 106\degree$

$2(10x-23)\degree = 254\degree$

$(10x-23)\degree = 127\degree$

$10x-23 = 127$

$10x = 127+23$

$10x = 150$

$x = \frac {150}{10}$

$x =15$

On each 3 days derrik rode 6.45 km to school, 150 meters to the library, and then 500 meters back home. How many kilometers did

Andrew [12]

Just add all 3 numbers up together:

6.45+ 0.15+0.5

=7.1

Since it was three days multiply the 7.1 by three

=7.1x3

=24

So for three days derrick rode for 24 km
