Question

Having troubles with inequalities.. 3.8x + 14.5 < 32

Answer 1

Answer: x < 4.6 rounded to the tenths

Explanation:

3.8x + 14.5 < 32

subtract 14.5 on both sides.

3.8x < 17.5

divide by 3.8 on both sides.

x < 4.60526316

Answer 2

`3,8x + 14.5 < 32\\ 3,8x<32-14,5\\ 3,8x<17,5\ /:3,8\\ x<(17,5)/(3,8)\\ \\ 17\frac12 :3\frac45=(35)/(2) :\frac{19}5=\frac{35}2\cdot \frac5{19}\\=(175)/(38)=4(23)/(28)\\ x<4(23)/(28)\\ x\in (-\infty;4(23)/(28))`
