Question

-2/5 x - 9 < 9/10???

Answer 1

Can you help me???

Answer 2

i might probably get this wrong (i have so many people here to correct me :D)

q+12-2(q-22)> 10

2(q-22)+q+12>10+2(q-22) additive inverse

q+12> 10+2(q-22)

q+22>10+ 2q-44 simplify

(34)+ q+22 > 2q-34 +(34) additive inverse

q+ 56 > 2q

56> q

Answer 3

Umm idk... Can anyone else give there opinion?

Answer 4

\[-\frac25 x - 9 < \frac9{10}\]First You want to isolate the monomial with x, so:\[\implies -\frac25 x<\frac9{10}+9\] follow so far?

Answer 5

\[9+ \frac9{10}= {99\over10}\]\[\therefore -\frac25 x<{99 \over 10}\]
Next you want to get rid of the co-efficient of x...

Answer 6

thanks!

Answer 7

lol wrong problem

Answer 8

that was for the last post

Answer 9

i copy and pasted

Answer 10

You do that by multiplying both sides by -5/2... Note that when multiplying both sides by a negative number flips the < sign to >\[-\frac52 \cdot-\frac25\cdot x>-\frac52\cdot {99 \over 10}\]\[\implies 1\cdot x>-{99 \over 4}\]\[\implies x>-24{3 \over 4}\]
