Answer:
18 and 20, 4
Step-by-step explanation:
Math reasoning 1:
Set the first number as x and the other one as x+2 because it is a consecutive even number.
x+x+2=38
2x=36
x=18
18+2=20
The 2 consecutive numbers are 18 and 20
Problem solving 1:
Write out equation first, set the unknown number as x
5+x=9
x=4
2.60 + 3.56 = 6.16
6.16 + 3.82 = 9.98
9.98 + 5.116 = 15.096
15.096 + 5.16 = 20.256
20.256 + 6.16 = 26.416
The final answer is 26.416

720=x(0.09)(4)
720=0.36x
x=2000
