Answer: p=0
Step-by-step explanation: Hope this help :D
Let's solve your equation step-by-step.
−1=p−1
Step 1: Flip the equation.
p−1=−1
Step 2: Add 1 to both sides.
p−1+1=−1+1
p=0
25 students
194 balloons
194/25 = 7.76
Each student gets 7 balloons, 7 x 25 = 175 balloons will be used
194 - 175 = 19 balloons remaining (Answer to part 1 of this question)
If each student needs 8 balloons
8 * 25 = 200
200 - 194 = 6 ballons needed (Answer to part 2 of this question)
We also could have found the answer to part 2 by saying that we had 19 balloons left over when the students each were given 7 balloons
Each student needs another 1 balloon = 25 balloons,
We have 19 left over
25 - 19 = 6 balloons need to be purchased (we got the same answer both ways so it is very likely we have the correct answer)
738 is a bigger number than 649
There are 17 members who are only in gymnastics, 7 who are only in chess, and 3 who are in both.
17+3+7=27
800-27=773
