Question

ПОМОГИТЕ СРОЧНООО!!!​

Answer 1

$3) \frac{2}{3} x-15<20$

$2x-45<60$

$2x<60+45$

$2x<105$

$x<\frac{105}{2}$

5)

$31-\frac{29}{7} x>2$

$217-29x>14$

$-29x>14-217$

$-29x>-203$

$x<7$

x∈(-∞,7)

6)

$30,08<-\frac{8}{9} x-1,92$

$\frac{752}{25} <-\frac{8}{9} x-\frac{48}{25}$

$6768<-200x-432$

$200x<-432-6768$

$200x<-7200$

$x< -36$

x∈(-∞,-36)
