- 4/5*9x +4/5*20 - 3x= 4/5x- 6
-36/5*x+16-3x-4/5*x= -6
-36/5*x-15x/5-4/5*x=-6-16
-55/5*x=-22
-11x= -22
x= -22:(-11)
x=2

-4/5(9*2-20)-3*2=4/5*2-6
-4/5*(-2)-6=8/5-6
8/5-6=8/5-6

Solve for x. Give your answer in simplest radical form
Tasya [4]
Use the Pythagorean Theorem to find the length of the side marked "x."
x^2 + (10 mi)^2 = (13 mi)^2.  Thus, x^2 + 100 mi^2 = 169 mi^2.
Next, x^2= (169-100) mi^2, or x^2 = 69 mi^2.  Find the positive square root of both sides of this equation.  What is it?

Ben has 50 drinks and paid 2$ for each. What is 67% of the final price ?
Debora [2.8K]

67% of final price is $67.

Step-by-step explanation:

Given,

Number of drinks Ben has = 50

Amount paid for each drink = $2

Amount paid for 50 drinks = 50*2

Amount paid for 50 drinks = final price = $100

67% of final price = \frac{67}{100}*100

67% of final price = \frac{6700}{100}

67% of final price = $67

67% of final price is $67.
