The other answers don't divide into rational numbers
30,27,24,21,19,16,13,10,7,4,1,-2,-5,-8,-11,-14,-17,-20,-23,-26
just take away 3 from each number
Answer:
-21
28
Step-by-step explanation:
1) if r = -4
Substitute r = -4 in 3r - 9
= 3 * (-4) - 9
= -12 - 9
= -21
2) ( 4 / 7 ) * x = 16
4 * x = 16 * 7
x = 4 * 7
x = 28
