Write an algebraic expression for this verbal expression: One-half the sum of three times "m" and 7, divided by the difference between 9 and the quantity of four times "m"

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

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,
