Step-by-step explanation:
Divide the numerator and denominator by their gcf (25)
75/25= 3
100/25= 4
Final answer: 3/4
Answer:
1.89x + 5.19y = 31.62.
Step-by-step explanation:
Let the pagke of hot dags be x
Let the pakage of hamburgers be y
Now they total up tp 8 packages.
xEliminate the cost
x+y=8
y=8-x
Cost of hotdogs = $1.89
Cost of hamburgers = $5.19
1.89x+5.19y=31.62
1.89x+5.19(8-x)=31.62
1.89x+41.52-5.19=31.62
-3.3x=--9.9
x=3
y=8-3
y=5
Explanation:
Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.
the optimal way is to do it with Cramer's rule.
First, find the determinant and then find the determinant x, y, v, u.
Afterward, simply divide the determinant of variables by the usual determinant.
eg.
and etc.
I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.
