Answer:

12

Step-by-step explanation:

1st of all we should let the ration of boys to girls be 2x and 3x.

After that we should make the sum between 2x and3×and the sum of 2numbers is equal to 30

i.e.2x+3x=30

Then ,by solving this eqation we get the value of x=6

After that put the value of x in the number of boys

i.e.

2x=2×6=12

Hence ,the number of boys is 12

The points (1, 5) and (0, –2) fall on a particular line. What is its equation in slope-intercept form?
Savatey [412]

The equation of the line in slope intercept form is y = 7x - 2

<h3>How to find the equation of a line?</h3>

The equation of the line can be solved with the following equation.

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore,

m = -2  - 5 / 0 - 1 = -7 / -1

m = 7

Hence, using (1, 5)

y = 7x + b

5 = 7(1) + b

5 - 7 = b

b = -2

Therefore,

y = 7x - 2

Hence, the equation of the line in slope intercept form is y = 7x - 2
