Answer:
$15 per pair
Step-by-step explanation:
We know that the total amount of money she spent on the shoes (without discount) is 3x. Since she used a $10 off coupon, the money she spent is 3x - 10, since $10 off means - 10. And this amount equals $35:

Your answer is x = 2.92 = 3.
To answer this question you need to use trigonometry, so the first step is to identify the hypotenuse, opposite, and adjacent.
Because the angle 73 is in the bottom corner next to the length x, we know that the length x is the adjacent. The length 10 is opposite the right angle so this must be the hypotenuse.
We know that cos(θ) = adjacent/hypotenuse, so we can substitute in what we know:
cos(θ) = adjacent/hypotenuse
cos(73) = x/10
Now we can rearrange for x:
cos(73) = x/10
× 10
cos(73) × 10 = x
Finally we just type this into the calculator and get the answer as 2.92 or 3.
I hope this helps!
So firstly, you want to foil - (7v^4 + 6) [Think of the minus sign as -1]: 
Next, combine like terms and your answer will be: 
Answer:
this an example not the answer i don't know the answer
E is between D and F.
Given: E is between D and F
Prove: DE = DF − EF.
Statements Reasons
1. E is between D and F Given
2. D, E, and F are collinear points, and E is on ¯DF Definition of between
3. DE + EF = DF Segment Addition Postulate
4. DE = DF − EF Subtraction property of equality
2. If →BD divides ∠ABC into two angles, ∠ABD and ∠DBC, then m∠ABC = m∠ABC - m∠DBC.
