Answer:

x =20

Step-by-step explanation:

As a line is 180 degrees

So 7x + 40 would be 180, which would lead us with the equation:

7x+40=180

=7x =140 (minus both sides by 40)

=x =20 (divide both sides by 7)

Explain how to subtract 7.6 from 20.39

ludmilkaskok [199]

There are different methods of subtraction. Break up the sum into different parts. 20 - 7 is 13. 0.39 - 0.60 requires borrowing 1 unit from the 13 to make 1.39 - 0.60. This makes 0.79. Add the two results together: 12 + 0.79 = 12.79.
