The answer should be 10, double check though.
Answer:
get 1 … what? free? half-price? something else?
Let x= price of 1 item
Then 3x= price of 3 items
Buy 2 , get 1 free
Total cost =2x
Discount =3x−2x=x
Discount percentage =x/(3x)=0.333…=3313%
Buy 2 , get 1 half price
Total cost =2x+0.5x=2.5x
Discount =3x−2.5x=0.5x
Discount percentage =0.5x/(3x)=0.1666…=1623%
Answer:
17.0
Step-by-step explanation:
If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.
Since this is an equilateral triangle, TV=VX. You can set TV equal to VX to solve for the value of x. The expression would be 10x-26=5x+9. Subtract 5x from both sides to get 5x-26=9. Add 26 to both sides to get 5x=35. Lastly, divide by 5 to get x=7.
So, your answer would be 7 degrees. Hope this helps!
