Hi there!
To add fractions there are three simple steps:
1. Make sure the bottom numbers (denominators) are the same. → In your case you're all good, both your denominators are 8.
2. Add the top numbers (numerators) and put that answer over the denominator :
-3 + 7 = 4 → 
3. Simplify the fraction (if needed). → In your case, you do need to simplify your fraction :
Divide both your numerator and denominator by 4 to get your simplified fraction :
4 ÷ 4 = 1
8 ÷ 4 = 2
Your simplified fraction is : 
There you go! I really hope this helped, if there's anything just let me know! :)
-3i+3/4+2i-9/3-3i=(3/4-9/3) +(-3i+2i-3i)=(3/4-3)+(-4i)=(3/4-12/4)-4i=
=-9/4-4i
True. Complementary angles are 90 degrees.
Answer:
Breyana paid 88% of the dress's original price.
Step-by-step explanation:
We are given the following in the question:
Let x be the original price of dress.
The dress is on sale for 20%.
Price of dress after discount =
Breyana will also have to pay 10% sales tax on the discounted price of the dress.
Price of dress after discount =
Total cost of dress =
We have to calculate percentage of original price paid by Breyana
Thus, Breyana paid 88% of the dress's original price.
9x ten to the power of 4 is written as 9x10^4
10^4 is 1 with 4 0s after it, 10000
So, 9x10000=90000
