Drag the tiles to the correct locations on the image. neil drives at an average speed of 60 miles/hour to reach his destination 480 miles away. on the way back, he decides to increase his speed to try to save at least one hour. if the increase in his speed is x miles/hour, create an inequality to find the minimum increase in his speed. 7 + x 480 ≥ ≤ = x + 60 7 x + 480

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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
