Answer:
15:2 or 15 to 2
Step-by-step explanation:
They are asking for a ratio based on how many chaperones per student (in this case 15 students) In other words 15 students for every 2 chaperones.
Answer:
y=5
Step-by-step explanation:
Use the process of deletion. It means to add all the like variables. 11x+(-11x) is just 0 so it cancels out. -6y+5y is -y. -19+14 is -5. This leads to -y=-5. The variable can NEVER be negative. To get rid of the negative, just divide by -1 on both sides.
Dodecahedron is a 3D shape, usually when it ends with hedron it is 3D.
Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558
so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls
each team plays 9 games
( Team 1 plays team 2 3 times, team 3 3 times, team 4 3 times )
9 x 4 = 36 games total
