Can someone please answer my question and answer it correctly and please show work please answer my question

20% = 20/100 = 0.20

Step 1: 20% of 15 = 0.20*15 = 3

Right off the bat, we can eliminate choices A and B since they show 0.020 instead of 0.20

Choice C is eliminated because we add on the sales tax of $0.78 instead of subtracting it off.

Problem 26

Using a calculator, we see that 5/16 = 0.3125

Note that 16 = 2^4. The '4' indicates how many decimal places it terminates. This works for any fraction of the form a/(2^b) where a,b are positive whole numbers.

answer:

the correct answer to this question is d, because u will have to move the decimal point 4 times backwards

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
