Phil bought a pair of shoes that were 30% off. A sales tax of 6% was added to the sale price. If the original price was $50, how much did Phil pay for the pair of shoes, including tax?

$39

Step-by-step explanation:

Set it up as

x/50 = 100/100

Then take away the 30%

x/50 = 70/100

Then add the 6%

x/50 = 78/100

x is equal to 78 because it is 78% of the total

50 is equal to 100 because it is 100% of the total

Now if you solve for x you get

39

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
