How do I do this step by step

-1

Step-by-step explanation:

1. You would get rid of the denominator -> Which would be 2

2. You would then multiply both sides by 2

This gets you: 2x + 22 = 20

3. You then would combine like terms -> Subtract the 22 to the side of the 20

This would get you the value of 2x = -2

4. Solve for X which gets you -1

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
