Someone please answer number 15, 17, 19, 21, 23, 25, 27

Question 2

#15

$\\ \bull\tt\dashrightarrow x+9>15$

$\\ \bull\tt\dashrightarrow x>15-9$

$\\ \bull\tt\dashrightarrow x>6$

#17

$\\ \bull\tt\dashrightarrow 5x+15\leqslant -10$

$\\ \bull\tt\dashrightarrow 5x\leqslant -10-15=-25$

$\\ \bull\tt\dashrightarrow x\leqslant \cfrac{-25}{5}$

$\\ \bull\tt\dashrightarrow x\leqslant -5$

#19

$\\ \bull\tt\dashrightarrow 6x\geqslant -0.3$

$\\ \bull\tt\dashrightarrow x\geqslant (-0.3)/(6)$

$\\ \bull\tt\dashrightarrow x\geqslant 0.05$

#21

$\\ \bull\tt\dashrightarrow (1)/(4)x>(1)/(2)$

$\\ \bull\tt\dashrightarrow x>(1)/(2)* 4$

$\\ \bull\tt\dashrightarrow x>2$

#23

$\\ \bull\tt\dashrightarrow 2.1x\geqslant 6.3$

$\\ \bull\tt\dashrightarrow x\geqslant (6.3)/(2.1)$

$\\ \bull\tt\dashrightarrow x\geqslant 3$
