Answer:
The number of girls in Mr Brown's Class were:
7
Step-by-step explanation:
Let the number of girls in Mr. Browns Class be 'x'
Then the number of girls in Mrs Pitt's Class are: x+4
( Since,it is given that:
there are 4 more girls in Mrs Pitt's class than Mr browns class )
Now, five girls moved from Mrs Pitt's class to Mr browns class.
This means that now,
The number of girls in Mr Browns class are: x+5
and Number of girls in Mrs Pitts class are: x-1
( Since, x+4-5=x-1)
Now, as we are given that:
There are twice as many girls in Mr browns class as there are in Mrs Pitt's this means that:
x+5=2(x-1)
x+5=2x-2
2x-x=5+2
x=7
Hence, the number of girls in Mr Brown's Class were:
7 girls.

Answer:</h3>
25°
<h3>
Step-by-step explanation:</h3><h3>
</h3>
<em>Angles in a circle add up to 360°</em>
5a + (a + 60) + (2a + 100) = 360
5a + 3a + 160 = 360
5a + 3a = 8a
8a + 160 = 360
<em />
<em>Make a the subject</em>
8a + 160 = 360
8a = 200
200 ÷ 8 = 25°
