Achoir director at your school wants to divide the choir into smaller groups there are 24 sooranos 60 altos and 36 tenors . each group will have the same number of each type of voice what is the greast number of tje group that can be formed

The question has a typo in it...so if you mean least: 2 groupsgreatest: 12

Step-by-step explanation:

Least:

24, 60, and 36 are all even numbers, so they can divide by 2 so each group would have 12 Sopranos, 30 Altos, and 18 tenors.

Greatest:

24, 60, and 36 can all be divided by 12. So, each group would have 2 Sopranos, 5 altos, amd 4 tenors.

probability for j is 1/4

while

a is 1/6

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
