5 x + 30 = 5 ( x + 6 )
( 4 / 5 ) ÷ ( 6 / 5 )
= ( 4 / 5 ) x ( 5 / 6 )
= 4 / 6
= 2 / 3

5x + 30 can be factored down to 5(x + 6).
4/5 divided by 6/5 is the same as 4/5 multiplied by 5/6, which gives you 4/6, or 2/3.

5x+30 = 5(x+6)
4/5 divide by 6/5 = 4/5 times 5/6 = 4/6 = 2/3

I'm not sure about factoring 5x+30, it's in a simple form already...but solving for x is...
5x+30=0
5x=-30
x=-6
Dividing fractions...just take one of their reciprocals and multiply
like this:
(4/5)/(6/5)
=(4/5) X (5/6)
and you just multiply the top by the top, and the bottom by the bottom:
20/30
simplify:
2/3

5x+30=0. factor a 5 out on the left side.
5(x+6)=0
5=0 (false) so x+6=0....solving for x, x = -6.
4/5 / 6/5 multiply the denominator by its reciprocal to get a 1 in the denominator. You must also muliply the top by the same reciprocal to keep everything equal so
(4/5)*(5/6) / (6/5) *(5/6)
simplify:
4/6 / 1 or 4/6.

5x+30 =
factor out the 5 to get:
5(x+6)
4/5 divided by 6/5 =
change the operation to multiplication and flip the second fraction to get:
4/5 * 5/6
after canceling the top and bottom 5's you get
4/6
reduce top & bottom by 2 and your answer is:
2/3

4/5 divided by 6/5 is... 4/6 is the answer

Well, you just have to put 0 where the question marks is and solve for x...
so
5x+30=0
then move the 30 over so
5x= -30
then divide by 5
x= -6
for the 2nd one... 4/5 / 6/5
yea...not quite sure...

1)
If we assume that
5x+30 = 0
5x = -30
x = -30/5
X = -6
2)
4/5 devided by 6/5
= 4/5 * 5/6
= 4/6
= 2/3

5x+30=
you can take a 5 out of both numbers so...
5(x+6)
4/5 divided by 6/5
first you do the reciprical of 6/5 which is 5/6
then u mult.
4/5 * 5/6
2/3 would be ur answer
