Answer:
<h2>x = 20</h2>
Step-by-step explanation:
The angles 7x° and (x + 20)° are supplementary angles.
Supplementary angles add up to 180°.
Therefore we have the equation:
7x + (x + 20) = 180
7x + x + 20 = 180 <em>subtract 20 from both sides</em>
8x = 160 <em>divide both sides by 8</em>
x = 20

4(5.6) = 4(6.0 - 0.4) = 4(6.0) - 4(0.4) = 22.4
16.
4(6 + 7) = 4(6) + 4(7) = 52

14(10 - 5) = 14(10) - 14(5) = 70
