Question

I'm having trouble with getting the answer to this equation once i get the answer i'm supposed to round to the nearest hundreth the equation is: 7.23x+16.51=47.89-2.55x

Answer 1

try multiplying everything by 100 to make everything easier

723x + 1659 = 4789 - 255x

does that help?

Answer 2

@CailynChanel: Can you elaborate on what you've done and what part of it is confusing you?

Answer 3

the answer is 3.2
the answer is 3.17611336 so if you round the 7 to the 1 it gets you: 3.2

Answer 4

Even if that is the right answer, you only rounded it to the nearest tenth @CubanLover

Answer 5

Answer 15

ok

Answer 16

well I subtracted47.89 from each side and got 40.66x+16.51=2.55 then i added 16.51to each side and got40.66x=19.05 then i divided each side by 40.66 and got .469, this is the way I learned how to these problems, but when i go back to check my answer it doesn't come out right.

Answer 17

here is my work plp

Answer 18

723x + 1659 = 4789 - 255x

Add 225x to both sides; subtract 1659 from both sides:

723x + 255x = 4789 - 1659

978x = 3130

Divide both sides by 978:

x = \(\frac{3130}{978}\)

Simplify that to decimals..

Answer 19

I'm pretty sure 9.88 is incorrect

Answer 20

@CubanLover, you added 7.23 + 2.55 and got 9.88. How?

Answer 21

@CailynChanel if you subtract something from the left or right side of the equation you should do the same to the other side too

Answer 22

7.23x+16.51=47.89-2.55x

if you subtract 47.89 from the right side to cancel...you must subtract 47.89 on the left side as well

7.23x + 16.51 - 47.89 = -2.55x

does that make sense?

Answer 23
