Answer:
No. of boys = 15
Step-by-step explanation:
Given that,
The ratio of boys to student is 3:7.
Number of girls in the school = 20
We need to find the number of boys in the school.
Let there are 3x boys and 7x number of students.
No. of girls = Total students - no. of boys
= 7x-3x
= 4x
ATQ,
4x = 20
x = 5
No. of boys = 3x
= 3(5)
= 15
Hence, there are 15 boys in the school.


Answer:
A) the y-intercept of g(x) is less than the y-intercept of f(x).
Answer:
y=7x+4
Step-by-step explanation:
slope- intercept form is y=mx+c
m=7
so y=7x+c
substitute (0,4) into y=7x+c
so 4=(7x0)+c
c=4
so y=7x+4
30/5 is 6, so c/3 is 6, and c is 6x3, so c is 18.
