Question

help me solve this linear inequality.....

Answer 1

\[1-5/9x \ge7\]

Answer 2

@jhonyy9

Answer 3

\[1-\frac{5}{9}x \geq 7?\]

Answer 4

@.Sam. this is the linear inequality i need solved

Answer 5

multiply both sides by 9

Answer 6

what do you get?

Answer 7

\[1-5x \ge7 @.Sam im \not sure\]

Answer 8

@.Sam.

Answer 9

\[1 - \frac{ 5 }{ 9 }x \ge 7\] To solve for x, you want to get rid of 1. You can get rid of 1 by subtracting 1 from both side.
So your inequality should finally look like: \[-\frac{ 5 }{ 9 }x \ge 6\]
Next you want to get rid of -5/9. You can do that by multiplying it by -9/5 from both side.
-9/5 x 6 = -10.8
This mean that x = -10.8

Answer 10

Let me check my work if I did anything wrong.

Answer 11

Okay, I checked it. x is equal to -10.8. I hope this help! Any question?

Answer 12

@GoldPhenoix how did u get -9/5x6=10.8

Answer 13

thanks 4 ya help @GoldPhenoix

Answer 14

Well. You want to cancel out: \[-\frac{ 5 }{ 9 }\] right?

Answer 15

ok

Answer 16

So you have to times it by \[-\frac{ 9 }{ 5 }\] Why? Well let see, what is -9/5 x -5/9?

Answer 17

45/45

Answer 18

45/45 = 1. So you cancel out 5/9 by multiplying it by 9/5. If you multiply it by 9/5, then you have to do it the other side.

Answer 19

right

Answer 20

so -10.8 is the solution set?

Answer 21

If you have a fraction with a variable and you want to cancel out the fraction, ex: \[\large \large \frac{ 1 }{ 2 }x\] You must flip the fraction. ex: \[\frac{ 1 }{ 2 }x \times \frac{ 2 }{ 1 } = 1x\]

Answer 22

Yes, the solution or x is -10.8.

Answer 23

You can check it if you want. :)

Answer 24
