Step-by-step explanation:
All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.
Answer:
Each sweater costs $8.30
Step-by-step explanation:
j = jeans
s = sweater
3j + 3s = 105.69
3(26.93) + 3s = 105.69
80.79 + 3s = 105.69
-80.79 -80.79
3s = 24.9
/3 /3
s = 8.3 ($8.30)
Check:
3j + 3s = 105.69
3(26.93) + 3(8.3) = 105.69
80.79 + 24.9 = 105.69
105.69 = 105.69

Answer:
25.12cm
Step-by-step explanation:
So we first find the area of the circle on top:
area= 
or 3.14 x
which equals 12.56
Then we multiply it by 2:
12.57 x 2 = 25.12
So the lateral surface area is 25.12cm
