Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
I believe it is the 28th person that will get both
Answer:
I believe it is -17.5. Tell me if I am wrong
Step-by-step explanation:
3x + 5 = x - 10
-x -5 -x -5
2x = -15
x = -7.5
3(7.5) + 5
= 22.5 + 5
= -17.5
