<h3>Given:</h3>
The ratio of number of girls and boys in a class of 30 students is 7:8
<h3>To Find:</h3>
The ratio of number of girls and boys if 5 new boys admit in the class.
<h3>Assumption:</h3>
Let the number of students be x.
<h3>Solution:</h3>
According to the question,
7x + 8x = 30
or, 15x = 30
or, x = 
or, x = 2
7x = 7(2) = 14
8x = 8(2) = 16
There were 14 boys and 16 girls in the school.
After admitting 5 new boys, we get
14 + 5 = <u>19</u>
The ratio of number of girls and boys now is 16:19.

Answer:
5/2
Step-by-step explanation:
The formula for slope can defined as y2-y1/x2-x1. So we'll take 17.5-7.5 which is 10. 7-3 is 4. Now we have 10/4. This can be simplified to 5/2.
Answer:
-10
Step-by-step explanation:
(1/5)x+4=2
5(1/5)x+4=2)
x+20=10
x = -10
