Can you show the paper more? I can't see what I need to know in order to solve it...

Answer: Sometimes true</h3>
========================================================
Explanation:
-8+d is positive only when d > 8
Here's why
-8+d > 0
-8+d+8 > 0+8 .... add 8 to both sides
d > 8
So if Jessica said "d is greater than 8", then her claim would always be correct.
However, her claim is sometimes true.
Two counter examples could be when d = 1 and d = 2.
If d = 1, then -8+d = -8+1 = -7 which isn't positive.
If d = 2, then -8+d = -8+2 = -6 which also isn't positive.
Basically if d is anything smaller than 8, then you'll have -8+d be negative.
If d is something larger than 8, say d = 9, then -8+d = -8+9 = 1 which is finally positive.
The answer is x=12 hope it helps

Answer:
$1799
Step-by-step explanation:
We simply work backwards and write out an equation.
Lets call the initial price P.
First we have 15% off the initial price P which means that we are only paying 85% of the initial price: .85*P.
Next we use a coupon for 20% off the reduced price which means we only pay 80% of the reduced price: .80 * (.85 * P)
We know that the price paid was $1223.32, set that equal to .80 * (.85 * P)
and we find that P is $1799
