Answer:
15 teams, 4 girls and 3 boys on each team.
Step-by-step explanation:
What's the greatest common multiple of 60 and 45? It's 15.
This is the greatest number of teams that can be formed.
60/15 = 4; thus, there will be 4 girls on each team.
45/15 = 3; thus, 3 boys on each team
We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
Answer:
AB = 21
Step-by-step explanation:
The midpoint divides the segment into two congruent parts, so you have ...
AB = BC
x +5 = 2x -11 . . . substitute the given expressions for AB and BC
16 = x . . . . . . . . add 11-x
Then the measure of AB is ...
AB = x +5 = 16 +5 = 21
