Pleaseeee helpppppp!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Answer 1

Step-by-step explanation:

2)$x - 7 > 10$

$= x - 7 + 7 > 10 + 7$

$= x > 10$

3)$3x \leqslant 21$

$= \frac{3x}{3} = \frac{21}{3}$

$= x \leqslant 7$

4)$5a - 2 < 18$

$= 5a - 2 + 2 < 18 + 2$

$= 5a < 20$

$= \frac{5a}{5} < \frac{20}{5}$

$= a < 4$

5)$2t + 8 > - 4(t + 1)$

$= 2t + 8 > - 4t - 4$

$= 2t + 8 + 4 > - 4t - 4 + 4$

$= 2t + 12 > - 4t$

$= 2t + 4t + 12 > - 4t + 4t$

$= 6t + 12 > 0$

$= 6t + 12 - 12 > 0 - 12$

$= 6t > - 12$

$= \frac{6t}{6} = \frac{ - 12}{6}$

$= t > - 2$
