A.6/5 divided by -3/2

Dmitriy789 [7]

A is -12/15 (4/5)
B is 35/12
C is 56
D is 8/15
Sorry if any of these are wrong.
To check them, turn any mixed number into an improper fraction. Then, multiply by the reciprocal. Ex: 4/0 divided by 1/3
X reciprocal- 4/0 times 3/1

What is 3x+4= -15? How would you get a negative number?

bulgar [2K]

Answer:

$x=-\frac{19}{3}$

Step-by-step explanation:

$3x+4=-15$

$3x+4-4=-15-4$

$3x=-19$

$\frac{3x}{3}=\frac{-19}{3}$

$x=-\frac{19}{3}$

What is the y-coordinate of the point that divides the directed

e-lub [12.9K]

Answer:

(D)5

Step-by-step explanation:

Given the point J(-3,1) and K(8,11).

The line segment that divides the segment from J to K in any given ratio can be determined using the formula.

$P(x,y)=\left(\dfrac{mx_2+nx_1}{m+n} ,\dfrac{my_2+ny_1}{m+n}\right)$

In the given case:

$(x_1,y_1)=(-3,1), (x_2,y_2)=(8,11)$ , m:n=2:3

Since we are to determine the y-coordinate of the point that divides JK into a ratio of 2:3, we have:

$\dfrac{my_2+ny_1}{m+n}=\dfrac{2*11+3*1}{3+2}\\\\=\dfrac{22+3}{5}\\\\=\dfrac{25}{5}\\\\=5$

The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:3 is 5.

The correct option is D.
