Answer: 42.50
Step-by-step explanation: sale price is the price at which something sells or is sold at after its price has been reduced
1/6 of a mi - 1 day, 2/6 of a mi- 2 days, 3/6 of a mi- 3 days, 4/6 of a mi- 4 days, 5/6 of a mile - 5 days, 1 mile - 6 days, 1 1/6 mi - 7 days, 1 2/6 mi - 8 days , so on & so forth, do you understand ?
By 4 becuase this will change the -4y to -16y , then adding the 2 equations will eliminate y.
D
1. That is a right triangle, what means that it has a angle of 90°, so you can calculate the value of "x" "as below:
Tan(α)=Opposite leg/Adjacent leg
The angle α is 60°, so the opposite leg is "x" and the adjacent leg is 5.
2. When you substitue these values, you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(60°)=x/5
x=(5)(Tan(60°)
x=5√3
Then, the answer is: The value of "x" is 5√3
