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


Sagot :

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

Answer: x < 4.6 rounded to the tenths

Step-by-step 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
