I’m gonna assume it’s 5x(2)+45x
10x+45x=55x
Answer: all of them are correct! great job!!!1
Step-by-step explanation:
.4 is 40 percent because you move the decimal two spaces to the right so it would be 40 percent, same as the others!
The RF is 9. You could go to Easycalculations.com/statics/cumulative/relativefrequency to double check :)
First get rid of the exponent: 6x + 3 = 243. then subtract 3 from both sides: 6x = 240. lastly divide both side by 6: x = 40. be sure to check your work by plugging it back in.
