Based off of the information given, the answer is C.
The coin landed on tails 36 out of 100 times which means it landed on heads 64 out of 100 times.
You have to get y by itself. Divide by 7 on both sides to get 1.43x-11=y. Hope this helps! ;)
All real numbers.

Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
Expand: 4(a+2)=4a+8
Expand again: 14-2(3-2a)=4a+8
4a+8=4a+8
You subtract by 8 from both sides of an equation.
4a+8-8=4a+8-8
Simplify.
4a=4a
Then, subtract by 4a from both sides of an equation.
4a-4a=4a-4a
Finally, simplify.
4a-4a=0
0=0
True
All real numbers is the final answer.
Hope this helps you!
Have a nice day! :)
20 + 30 = 50 people in total
So in the 30 ,10 people were pranked and 10 did not, that means the other 10 people did not even listen to them or something.
But it is for sure that there are 50 people in total over there.
