Question

i need help desperately
solve - (3) <2x-1/5<0

Answer 1

add 1/5 to all terms
-3+1/5<2x<1/5
divide by 2 in all terms
-3/2+1/10<x<1/10

Answer 2

make sense?

Answer 3

ok ok i see thanks so much

Answer 4

is that the answer

Answer 5

Nope, you're not there yet :) From here, simply find what is -3/2+1/10. Then we will get (the number) < x < 1/10.

However, to solve for x, I have to know if it is stated that x is an integer? Anyways, if x is an integer, then x is any integer between (the number) and 0.

If x is a real number, then it is simply between (that number) and 0.

Hope this helped! :)

Answer 6

x is a real number

Answer 7

then just simplify the LHS and you are good

Answer 8

yup so x is between the number we previously got, and 1/10 :)

Answer 9

is the answer -1.4

Answer 10

i mean 1.4

Answer 11

Hi, it's me again :) Well -3/2 + 1/10 is actually -1.4. So great! Note that these type of questions require a range of numbers. So x is from -1.4 to 0.1 :) have a nice day! @darryl.hayes61
