A) 22:7
B) 29:22
29 - 7 = 22, so there are 22 yellow pencils.
There are 22 yellow pencils and 7 green pencils, so the ratio of yellow pencils to green pencils is 22:7.
There are 29 pencils, and 22 of them are yellow, so the ratio of all pencils to yellow pencils is 29:22.

Step-by-step explanation:
I just multiplied the 2 fractions and that is what i got.
Answer:
yes I think 6 is a solution to the equation
The area of a triangle is
(4.5feet)(5.75feet) and that would equal 12.9375 feet²
The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
