The richest president in the world is Sebastian Pinera, President of Chile with $2.4 billion.
|DF| = |DE| + |EF|
|DF| = 9x -36
|DE| = 47
|EF| = 3x+10
Substitute:
9x - 39 = 47 + 3x + 10
9x - 39 = 3x + 57 |+39
9x = 3x + 96 |-3x
6x = 96 |:6
x = 16
Put the value of x to the equation |EF| = 3x + 10
|EF| = (3)(16) + 10 = 48 + 10 = 58
Answer: |EF| = 58
$45+$18+$26-$21-$93
45+18=63
63+18=81
81+26=107
107-21=86
86-93=-7
Answer:
3 units right, 4 down = (x+3, y-4)
3 units left, 4 up = (x-3, y+4)
4 units right, 3 down = (x+4, y-3)
