Answer:
x<7
Step-by-step explanation:
4(5−2x)−3x>8x−113
−11x+20>8x−113
−11x+20−8x>8x−113−8x
−19x+20>−113
-20 -20
-19x>-113
/-19 /-19
(flip the sign)
x<7
i can't do the greater than or equal to sign so just remember to add that in :)
Answer:

Step-by-step explanation:

This gives x= 
Using the formula that 
3% = 3/100 = 0,03
When it's compount interest it's 1,03 because you gain 3% more from what you already have.
All you need to do
1,03•2000=2060$ for the first year
And then for the second year, you take the actual amount after one year of 3%
1,03•2060=2121,8
After two years, there will be 2121,8$
Let's rewrite the information then figure out the answer.
DVD: $9.00 originally but on sale with an 80% discount.
80%=0.80
9.00(0.80) = $7.20
$9.00 - $7.20 = $1.80
Thus, the sales price is: $1.80
(250 * 12) / 39,000 = 3000/39,000 which reduces to 1/13 <==
** I multiplied 250 by 12 to get the cost per yr
