Help me please with this question thank uu

green buttons = 87 buttons

Step-by-step explanation:

pink : blue = 2 : 7

blue : green = 3 : 4

Here we see blue button being common. So equal it with others.

pink : blue = 2 : 7 (* 3)

pink : blue = 6 : 21 from theory 1

blue : green = 3 : 4 (*7)

blue : green = 21 : 28 from theory 2

Then the total ratio is

           pink : blue : green = 6 : 21 : 28

so total there are ( 6 + 21 + 28 ) = 55 units

55 units ---> 170

1 units ---> 170/55

1 units ---> 3.09

So the number of green button is ( 3.09 * 28 ) = 87 buttons.

86

Step-by-step explanation:

P+B+G < 170 known

P/B = 2/7          p = 2/7 B

B/G = 3/4         B = 3/4 G

P = 2/7 * 3/4 G = 3/14 G

P+B+G = (3/14 G) + (3/4 G) + G

           = 55/28 G

55/28 G < 170

G < 86.55

Greatest number of Green should be 86

5050

hope this !

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
