I don't know what you mean by "Broken apart," but I'll do my best...
20 x 90 = 1800
9 x 7 = 63
1800 + 63 = 1863
I hope this helped you! :)
Answer:
option c
Step-by-step explanation:
<em>Step 1: Multiply each number in matrix A by -4</em>
( -4x-4 -4x-4 1x-4 )
( 1x-4 4x-4 7x-4)
( 2x-4 3x-4 3x-4)
( 16 16 -4 )
( -4 -16 -28)
( -8 -12 -12)
<em>Step 2: Multiply each number in matrix B by 8</em>
( 2x8 9x8 -9x8 )
( 8x8 8x8 -2x8 )
( 4x8 10x8 1x8 )
( 16 72 -72 )
( 64 64 -16 )
(32 80 8 )
<em>Step 3: Form the matrix of -4A + 8B by adding the correspondent numbers in the matrix.</em>
( 16+16 16+72 -4-72 )
( -4+64 -16+64 -28-16 )
( -8+32 -12+80 -12+8)
( 32 88 -76 )
( 60 48 -44)
( 24 68 -4 )
Therefore option c is correct.

Answer:
36.875
Step-by-step explanation:
(6 2/3) / (1 1/2) =
(20/3) / (3/2) =
20/3 * 2/3 =
40/9 =
4 4/9.........this would fill 4 4/9 containers
