Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:
Here, we have the equation:
And we divide both sides by 2:
To acquire:
So, we did <em>not</em> use the additive inverse property since we didn't add anything.
Instead, we used the<em> division property of equality</em> by dividing both sides by 2.
So, our answer is A.
And we're done!

Answer:
(b) 40°
Step-by-step explanation:
Angle x and the one marked 70° are alternate interior angles, so are congruent. The sum of the two base angles of the isosceles triangle is ...
x° +x° = 70° +70° = 140°
So, the remaining angle 1 in the triangle is ...
180° -140° = 40°
∠1 = 40°
C
20% increase
$50 + 20% = $60
1 is the answer hope this helps
