Step-by-step explanation:
From the simultaneous linear equation, we have the coefficient matrix as;
(3 4 5)
(2 -1 8)
(5 -2 7)
The x-matrix is Dx is given by;
(18 4 5)
(13 -1 8)
(20 -2 7)
Similarly, the y-matrix Dy is given by;
(3 18 5)
(2 13 8)
(5 -20 7)
Also,the z-matrix Dz is given by;
(3 4 18)
(2 -1 13)
(5 -2 -20)
Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136
If they each kept the same amount of the $50 prize, then we divide $50
by 2 people, giving each of them $25 winnings. Your question is then a
little confusing because it could be answered in two ways. Did they
each keep $20.75 out of their $25 winnings, or did the two of them keep
$20.75 in a combined total? Please read your question again to see
which might be the case. I'm answering on the assumption that they each
kept $20.75.
STEP 1:
divide total prize money by 2
= $50 ÷ 2
= $25 each won
STEP 2:
If they each kept $20.75
= $25 won - $20.75 each kept
= $4.25 each gave away
STEP 3:
multiply amount given away by 2 people
= $4.25 * 2 people
= $8.50 total given away
ANSWER: The total given to Romy is $8.50.
Hope this helps! :)
With this problem, it's essentially asking how many groups of 6 can fit into 324. We can do that simply by dividing 324 by 6 to get 54.
