Answer:
Step-by-step explanation:
Original cost = $32
Discount = 30% of 32
Selling price = 32 - 9.60 = $22.40
Tax = 6.75% of 22.40
= $ 1.51
Total cost with discount and tax = 22.40 - 1.51 = $ 20.89

From the diagram the altitude is 
Method 1: We can use Pythagoras theorem to find
We take the square root of both sides,
Method 2 Using Trigonometry
Answer:
x = -1
Step-by-step explanation:
5x + 3y = 26
- (6x + 7y = 21)
_________
-x - 4x = 5
-5x = 5
x = -1
The answer would be option M.: x-0.4x.
Answer:
x < -4
Step-by-step explanation:
Hello!
I don't see the drop-down menus, but I will try to help as best as I can...
Like any other equation, you are trying to get x by itself.
Our first step will be to subtract 13 from both sides.
-7x + 13 > 41
-7x > 28
Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.
-7x/-7 > 28/-7
Doing the above equation will provide us with x all alone on one side:
x < -4
Hope I helped!
