First solve for x in the first equation. So you'll have to substitute,
5(3x-7)=20
15x-35=20
Then add 35 to both sides.
15x=55
Divide 55 by 15.
So x = 3.66...
Then plug in 3.7 for x in 6x-8
6(3.7)-8
Its approximately 14.2
x - 4 = -12
I think x = -8 as if you decrease -8 by 4 it will leave us with the answer of -12
x = -8
Hope this helped,

I believe that you are correct.
Answer:
$132,000 X .0085 = $1,122 / 360 = $3.1166 X 164 = $511.13
One mill is one dollar per $1,000 dollars of assessed value.
In our case 8.5 mills equivalent to 0.0085.
So to get the assessed value for one day
we will get
$132,000 X .0085 = $1,122 / 360 = $3.1166
Now we have the value for one day,
For June 14, we will calculate the days from January 1st to date
total days are 164. i.e. 5*30+14 = 164
Finally, the seller owes
$3.1166 * 164 = 511.13
Answer:
a) 0.8( 8/10 gives 0.8)
b)0.7( if it was 7/100 it would have been
0.07)
c)3.5( by converting mixed fractions to improper fractions, that is, 3×2+1 and having the same denominator 2… we get 7/2… for the purpose of converting it to decimal, 7×5/2*5= 35/10… by moving one decimal place to the left, we get 3.5)
D) 2.5 ( the same way as c) 5*5/2*5: 25/10 or you can make it to be 5*50/2*50: 250/100 which still gives 2.5)
