5a+b = 5(6)+3 =3
10-r+5 = 10-(9)+5 =6
Answer:
The number of boys are 18 and the number of girls are 30.
Step-by-step explanation:
The ratio of number of girls to the boys = 3 : 5
Let the number of girls is g and boys is b initially.
b : g = 3 : 5
5 b = 3 g ..... (1)
Now, girls are 6 + g and boys are b - 9
So, the ratio is
(b - 9) : (6 + g) = 1 : 4
4 b - 36 = 6 + g
4 b - g = 42 .... (2)
From ( 1 ) and ( 2 )

And , g = 5 x 18/3 = 30
So, the number of boys are 18 and the number of girls are 30.
Answer:
59 F
Step-by-step explanation:
F=1.8C+32
Let C = 15
F = 1.8 (15) +32
Multiply 1.8 times 15
F = 27+32
F = 59
15 degrees C is 59 degrees F
