x=20

Step-by-step explanation:

Ques5) x value is 20 because 3x+6x=180

=>9x=180

=> x=180/9

=> x=20

Ques6) 6x= 6*x which is equal to 6*20=120

Ques7) 3x=3*x which is equal to 3*20=60

This is correct because 120+20=180 which is a straight angle given in the question. Hope this helped, Thank you.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
