At the ball game, 65% of the fans waved pom-poms. If 133 fans did not wave pom-poms, how many fans were there in all?

Answers

Answer: 380

Step-by-step explanation: Create an equation, so if 65% waved then 35% of the total (x) didn't wave, which are 133 people, so .35x=133, solve for x so x=133/.35 so x=380

your friend evaluates the expression when m = 10. is your friend correct? Explain your reasoning.

3m - 6 = 3(10) - 6
= 3(4)
=12

PLS HELP ASAP!

Answers

Answer:

yes

Step-by-step explanation:

3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

yes ,

3•10 = 30 - 6 = 24

now when you do 3(4) you get 12 and then subtract the 12 from the 24 and you get 12
