Solve 5x - 3.8 = -6.4

1. Write the equation

2. Do addition property of equality

3. Simplify

4. Division property of equality

5. Simplify again

-0.52

Step-by-step explanation:

1. 5x-3.8=-6.4

2. 5x-3.8=-6.4+3.8

3. 5x=-2.6

4. 5x=-2.6/5

5. -0.52

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
