The mean is 9.6
3+8+10+12+15= 48/5= 9.6
There are 4/7 boys, so there are 3/7 girls.
Let the total number of children be x.
4/7x = 8
1/7x = 8 ÷ 4
1/7x = 2
3/7x = 2 x 3
3/7x = 6
There are 6 girls.
3/4 of 3600..." of " means multiply
3/4 * 3600 =
10800/4 =
2700 <==
7.5 would be my best guess
Answer:
0
Step-by-step explanation:
–5(3 – q) + 4 = 5q – 11
-15 +5q + 4 = 5q -11
-11 + 5q = 5q - 11
+5q - 5q = -11 + 11
0=0
