The answer to the question
There are 100 tens in 1,000
M<ABC = m<EBD = 36 (vertical angles)
78 - x + 36 + 3x - 10 = 180 (straight angle)
Now solve for x
78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
- 68 -68 (subtract 68 on both sides)
2x = 58
x = 29
So given the formula 4 is going to be your first term 6 is the number you are multiplying/dividing! So 4x6 24 or -24
Answer: The 3 in 3,899 is 10 times the 3 in 4,385!
