Answer:
512
Step-by-step explanation:
the number of subsets of the set {1, 2, 3, ..., 9} is : 2^9 = 512
3x + (x+3) = 19
4x + 3 = 19
4x = 16
x = 4
y= x+3
y= 4+3
y= 7
" the quotient " means divide
(x/3) - 4 <== ur expression
Richard and Teo are 7 and 24.
7 times two is 14
24 is ten more than 14
31-7 is 24
Answer:
