Answer: 7.5k

=========================================

We simply add up the three expressions

k+2.5k+4k = 1k+2.5k+4k = (1+2.5+4)k = 7.5k

Because we don't know the value of k, we leave it as is.

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
