Answer:
A
Step-by-step explanation:
U can already eliminate C and D since the z needs to be with 2. A and B almost look the same but in the radicals the second number goes on top resulting in 5/6 which leads to A.
Answer:
Number of games = 4
Step-by-step explanation:
Let the number of games = x
Family Bowling Alley charges $1 for shoes and $4 dollars per game
If x games is played
Cost= 1+4(x)
Knight Owl Bowling charges $2 for shoes and $3.75 per game.
If x games is played
Cost = 2 + 3.75(x)
When the both cost are equal
1+4(x)= 2+3.75(x)
4x-3.75x = 2-1
0.25x = 1
X= 1/0.25
X= 4
Number of games = 4
C = 25 + 7h...c = 81
81 = 25 + 7h
81 - 25 = 7h
56 = 7h
56/7 = h
8 = h......so at 8 hrs, it will cost $ 81
