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.

Find the slope of the line passing through the points (8,-4) and (-7, -4).
Tju [1.3M]

Answer:

Step-by-step explanation:

slope=m=(Y2-Y1)/(X2-X1)

As given values

take,   (X1,Y1)=(-7,-4)

          (X2-Y2)=(8,8)

hence   X1=-7  ,  Y1= -4   ,  X2=8  , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

m=12/15    Ans

How to find slope and y intercept from the equation ax+by=c?
melisa1 [442]

solve for "y" so it is in the form y = mx + b.   "m" is the slope and "b" is the y-intercept.

ax + by = c

      by = -ax + c          <em>subtracted "ax" from both sides</em>

       y  = (-a/b)x  + c/b     <em>divided both sides by "b"</em>

Answer: slope is -a/b    and y-intercept is c/b
