The table shows the number of students in a class who play on a school team and/or are members of a school club:
eimsori [14]
This one is very simple.

create a simple equation to find out

15 = 12 + x

subtract 12 from each side

x= 3

the missing number is 3

or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.

hope I helped



ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then

a = 220 (t)
b =</span> 220 (t) +  220 (.25)

<span>And we want to know when these two equal eachother, as that's they will both detonate.

220t = 200 t + 200 (.25)
20t = 50 
t = 2.5</span>
