In the 6th grade classes, there are 4 girls for every 3 boys. if there are 24 girls, how many boys are there

18 boys

Step-by-step explanation:

So lets Write out an equation for the 4 girls for 3 boys. Let g be girls and b be boys.

4g=3b

To get from 4 to 24 we need to multiply by 6. We need  to multiply both sides by 6.

4g*6=3b*6

Multiply

24g=18b

There are 18 boys

what are you trying to solve here

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
