13. There are 16 sixth graders and 20 seventh graders in the Robotics Club. For the first project, the club sponsor wants to organize the club

members into equal-size groups. Each group will have only sixth graders

or only seventh graders.

Part A

How many students will be in each group if each group has the greatest

possible number of club members? Show your work

There will se 4 students in each groupo

Part B

If each group has the greatest possible number of club members, how

many groups of sixth graders and how many groups of seventh graders

will there be? Use numbers and words to explain your answer.

3 is greater then both of those numbers

the 3rd on is correct

step-by-step explanation:

16

step-by-step explanation:

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
