Answer:
3 -1 -2
5 1 6
Step-by-step explanation:
An augmented system has the coefficients for the variables and then the solution going across
Rewriting the equations to get them in the form
ax + by = c
-3x+y =2
3x-y =-2
5x+y = 6
The matrix is
3 -1 -2
5 1 6
Answer:
395/136
Step-by-step explanation:
(9 7/8)/(3 2/5) = (79/8)/(17/5) = (79/8)(5/17) = 395/136
Since 9 7/8 is larger than 3 2/5, it is an improper fraction.
B and C is the answer if you look at them closely.
259-85+62÷2 is the answer
Answer:
90 ft
Step-by-step explanation:
Times the length by the width of one side: 6 x 3= 18
Times 18 by 4 to get the surface area of the 4 rectangular sides: 18 x 4= 72
Times 3 by 3 to get the bottoms surface area: 9
Times 9 by 2 to get both the top and bottoms surface area: 18
Add 72+18 to get the total surface area: 90 ft
