Well, it should be 45 because 1/3 of the game would be 15 and 15+15 is 30 (2/3rds cost), so 15+15+15, 45, would be the full cost of the game
perimeter = 2L +2W
the problem states the length ( L) is 2 meters longer then width, so L = w+2
so perimeter =2(w+2) +2w
24 = 2(w+2) +2w
24 = 2w+4 +2w
24 = 4w+4
20=4w
w=20/4 = 5
Answer:
80 minutes
Step-by-step explanation:
1 hour=60 minutes
2 hours=120 minutes
-------------------------------
15/120=10/x
cross product
120*10=15*x
1200=15x
x=1200/15
x=80
Answer:
d = 3/4
Step-by-step explanation:
2.5 - d = 1.75
-2.5 -2.5
------------------
-d = -0.75
d = 0.75
d = 3/4
Answer:
15
Step-by-step explanation:
123=x+x+12+(x+12)*3
123=5x+48
75=5x
15=x
