Jennifer's teacher has marked this problem as one to recheck, but Jennifer cannot determine what she has done incorrectly. Identify Jennifer's error and write a correct solution.

Eight less than 2 times a number is 40. What is the number?

2x – 8 = 40 (line 1)

2x – 8 – 8 = 40 – 8 (line 2)

2x = 32 (line 3)

2x ÷ 2 = 32 ÷ 2 (line 4)

x = 16 (line 5)

2 x t divided by n

step-by-step explanation:

b

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

its totaly b

your welcome btw
