There are 18 students in the Math Club. Of the 18 students, 1/6 have red hair. How many of the students have red hair? Of the 18 students, 4/6 have brown hair. How many of the students have brown hair?

3 students with red hair

12 students with brown hair

Step-by-step explanation:

1/6 times 18 = 18/6 = 3 students with red hair

4/6 times 18 = (18 times 4)/6= 12 students with brown hair

Red=3

Brown=12

Step-by-step explanation:

So to find 1/6 of 18 you divide 18 by 6 which is 3.

red = 3

Then to find 4/6 well you've already found out 1/6 is 3 so all you need to do is times that by 4.

3x4=12

Brown = 12

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
