3. What is the value of the expression 5x -2 when = 3/4
yaroslaw [1]

Answer:

Step-by-step explanation:

Pay attention to the procedure:

(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values Then you have to do x squared before you multiply it by 5 like this: (5(100))^3/(10(5))^4 Now solve for what is in the top parenthesis. (500)^3/(10(5))^4 500^3=125000000 Now work on the denominator. Do what is inside the parenthesis first 10*5=50 Now (50)^4=6250000 Now divide the numerator and the denominator. 125000000/6250000 Which equals 20, Please check if I'm wrong but I think this is what you need

Put these in order from greatest to least.

86%, 3/4, 0.682, 0.67, 5/8, 0.41

^ I converted the above to decimals first and then arranged them that way. 

1/20 = 0.05 x 100 = 5%
