Answer:
Step-by-step explanation:
Hi the answer is simple all you need to do is focus it is the top row.
A suitable graphing caculator gives the result
X = 15 25/39
Y = 7 6/13
Z = 4 4/39
_____
If you want to solve this by hand, you can add 3 times the first equation to the second to get
... 5X -2Z = 70
and 5 times the first equation to the third to get
... 8X -11Z = 80
Then Cramer's Rule tells you the solutions for X and Z are
... X = (-160+770)/(-16+55) = 610/39
... Z = (560 -400)/39 = 160/39
From there, you can substitute into any of the equations to find Y. The first one might be most convenient.
... Y = 19 -X +Z = 19 -(15 25/39) +(4 4/39) = 8 -21/39 = 7 6/13
Answer:
i think it' =-8abc(a+b-c)
Step-by-step explanation:
Answer:
a) 34
b)$76.5
if each bag is 2.25 pounds then that can make 34.444 bags but if you want full then it is just 34. Since each bag is $2.25, you just multiply by 34 and you get 76.5
