2 apples for $1.50 and 8 apples for $6.50, is this a proportional relationship?

no

Step-by-step explanation:

$1.50×8=12$ US$ so 12$ for 8ap or 6.50$ for 8ap

if x = 1, then the answer is 3.5

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
