Let the first one be x, the second one is then x+1
x+(x+1)=81
2x=80
x=40
the two consecutive integers are: 40, 41
She kept the + 3 on the right side of the equation in her second step, she forgot to eliminate it..... there fore, it would have been -2x + 1 = x + 3 not -2x + 1 - 3 +3 = x+3
4.5*10^3/9*10^7=4.5/9*10^3*10^7=0.5*10^3*10^7. a^b*a^c=a^(b+c), so 10^3*10^7=10^(3+7)=10^10. 0.5*10^10=5*10^9, since we want to write in scientific notation where the leading number is bigger than one and smaller than 10.

Answer:
52°
Step-by-step explanation:
(I'm assuming lines JK and HI are parallel)
∠JKA and ∠HIA are corresponding so they are congruent.
Therefore, since ∠JKA is 62, so is ∠HIA. Then knowing the sum of interior angles of a triangle always must be 180, you can just do the math to get 52° as the remaining angle.
66° + 62° + ∠x = 180
∠x = 52°
