Arithmetic
Step-by-step explanation:
An arithmetic progression is characterised by the first term (a), number of terms (n) and common difference (d).
62,000 is reasonable (because of rounding)90*690=62,000
All positive integers less than or equal to 72<span />
Answer to written question:
3x + 10x + 7x = 180
Combine like terms
20x = 180
Divide by 20
x = 9
Smallest angle 3x = 3*9 = 27 degrees
Answer to question in picture:
30/6x-2 = 36/5x + 13
Cross multiply
30(5x + 13) = 36(6x-2)
Distribute
150x + 390 = 216x - 72
Subtract 150x
390 = 66x - 72
Add 72
462 = 66x
Divide by 66
x = 7
