3v - 13 < 6
3v<19
v<19/3

3v=7

v<19/3 or v>7/3


i dont quite understand the other two...

Awww thank you michelle!! *hugs*hugs*

No problem

Im doing these is math too

12. 4w 8 = 15 - 6w
10w = 7
answer: w=7/10


48. (k/4) divided by 13(k-1) = 3(k-3) divided by 14
i dont get this one, sorry lol


38. 3v - 13 < 6
3v<18
answer:v<6


46. 4b - 2.4 >over- 3r - .2

i dont get what u mean by this one..

When you have a < or > sign, you treat it like an = sign... If the number before the variable (k,v) is negative, you have to switch the < or > sign around..
