Answer:
Step-by-step explanation:
Discount = 20% of 129.99
= $26
Price after discount = 129.99 - 26 = $103.99
Tax = 8.5% of 103.99
= $8.84
Selling price including tax = 103.99 + 8.84
= $112.83
Amount saved = 129.99 - 112.83
=$ 17.16
Answer:
We save 16.18 dollars.
Step-by-step explanation:
First, I did calculations on how much money there would be with the discount.
129.99 times 0.2 equals 25.1 [So with the discount, I got 25.1 dollars off.]
129.99 - 25.1 = 104.89 [so with the discount, I just have to pay 104,89, now,]
Now, I did the calculations WITH the SALES TAX.
104.89 times 0.085 equals 8.92 [ so tax is actually 8.92 dollars.]
104.89 + 8.92= 113.81 [ SO, with TAX, the table costs 113.81.]
Now I see how much money I have saved.
104.89 - 113.81 = 16.18

The mixfraction 9(3/4) as a percent is 975%.
We have,
To express 9 3/4 as a percent, we can follow these steps:
Step 1: Convert the mixednumber to an improperfraction.
Multiply the whole number (9) by the denominator (4) and add the numerator (3) to get the numerator of the improper fraction. The denominator remains the same.
9 3/4 = (9 * 4 + 3) / 4 = 39/4
Step 2: Convert the fraction to a decimal by dividing the numerator by the denominator.
39/4 = 9.75
Step 3: Convert the decimal to a percent by multiplying by 100.
9.75 * 100 = 975
Therefore,
9 3/4 as a percent is 975%.

B. -3n – 2
C. -4n – 5
D. -5n – 6
Answer:
D) -5n-6
Step-by-step explanation:
-4(n+1)-(n+2)
-4n-4-n-2
-4n-n-4-2
-5n-4-2
-5n-6
Answer:
-(5 n + 6)
Step-by-step explanation:
Simplify the following:
-4 (n + 1) - (n + 2)
-4 (n + 1) = -4 n - 4:
-4 n - 4 - (n + 2)
-(n + 2) = -n - 2:
-4 - 4 n + -n - 2
Grouping like terms, -4 - 4 n - 2 - n = (-4 n - n) + (-4 - 2):
(-4 n - n) + (-4 - 2)
-4 n - n = -5 n:
-5 n + (-4 - 2)
-4 - 2 = -(4 + 2):
-5 n + -(4 + 2)
4 + 2 = 6:
-5 n - 6
Factor -1 out of -5 n - 6:
Answer: -(5 n + 6)
