Answer:

1) 4+5=9.

2)  2+(-6)=-4

3)  -3+(-7)=-10

4)  (-7)+3=-4

5)  9+(-4)=5

6)  -1+4=3

7)  5+(-5)=0

8)  -3+(-6)=-9

Step-by-step explanation:

In the given number lines, rightarrows represent positive integers and leftarrows represent negative integers.

1)

In first number line we have two rightarrows.

Rightarrow from 0-4 = 4

Rightarrow from 4-9 = 5

So, required sum is 4+5=9.

Similarly,

2)

2+(-6)=-4

3)

-3+(-7)=-10

4)

(-7)+3=-4

5)

9+(-4)=5

6)

-1+4=3

Find the value of x and the length of each side ​
AlladinOne [14]

The 3 sides of the triangle are  PR =  8.4, OR =  5.4 and OP =  3.1

Step-by-step explanation:

Step 1 :

Given

PR = 3x - 0.6

OP = x +  0.1

OR = x + 2.4

Also the 2 sides OR and PR are said to be equal.

So we have OR = PR

=> 3x - 0.6 =  x + 2.4

=>  x = 2.4 + 0.6 => x = 3

Step 2 :

we have ,

PR = 3x - 0.6 = 3(3) - 0.6 = 8.4

OR =  x + 2.4 = 3 + 2.4 = 5.4

OP = x + 0.1 = 3 + 0.1 = 3.1

Step 3 :

Answer :

The 3 sides of the triangle are

PR =  8.4

OR =  5.4

OP =  3.1
