Answer:
15 girls
Step-by-step explanation:
In all, there are 7+5 = 12 equal groups of students in the class, that in total make 36 people.
So there are 3 students in each small group.
Answer.
There are 7*3 = 21 boys and 5*3 = 15 girls.
Yes 45/45 = 1 +10 = 11
13 > 11
Answer:
x=27
Step-by-step explanation:
expanding the above expression we get
5x+5=4x+32
grouping numbers with coefficient of x at the left side and constant at the right side we get
5x-4x=32-5
x=27
Perimeter = 2L + 2W
22m= 2(5) + 2W
22= 10 + 2W
22-10=2W
12= 2W
