-25 15/19 + 9/1

get a common denominator of 19

they multiplied 9/1 * 19/19 = 171/19

-25 15/19 + 171/19 =

change the mixed number to an improper fraction

(19* 25 +15)/19 = 490/19

-490/19 + 171/19 =

add together

-319/19

now convert the improper fraction back to a mixed number

19* 16 =304  319-304=15

-319/19 =-16 15/19

Through: (-3,-4) and (0,4)
12345 [234]

Answer:

The slope = 8/3

Step-by-step explanation:

Let's find the slope between your two points.

(−3,−4);(0,4)

(x1,y1) = (−3,−4)

(x2,y2) = (0,4)

Use the slope formula:

m= y2−y1 / x2−x1

= 4 − −4 / 0 − −3

= 8/3

Answer:

m = 8/3

hope this helps and is right :)

Suppose RS is conjurated to MN. For each of the set of lengths, solve for X, and find the length of each segment.
NeX [460]

If RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

Given RS is congruent to MN.

We are required to find the value of x if RS is congruent to MN.

Congruent lines are those lines whose lengths are equal to each other.

1) RS=x+10, MN=2x+4.

Because the congruent lines have equal lengths so , RS=MN.

x+10=2x+4

x-2x=4-10

-x=-6

x=6

2) RS=3x-2, MN=x+6

Because the length of lines are equal,so RS=MN.

3x-2=x+6

3x-x=6+2

2x=8

x=4

3) RS=5x-10, MN=2x+20

The lengths are equal so RS=MN.

5x-10=2x+20

5x-2x=20+10

3x=30

x=10

Hence if RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

How to draw a diagram that shows 1/5 times 30 equals 6
Andrew [12]
Multiplying by 1/5 is the same as dividing by 5, so we can show a diagram of division. This can be done by constructing a horizontal line of length 30 cm and dividing it into 5 equal parts; each part will measure 6cm.
