Step-by-step explanation:
let E be weight of expensive nuts, C be cheaper nuts
E*8+C*5=10*6 value equation
E+C=10 mass equation
Solve it by any method, I will do determinants
Det: 8-5=3
E= (60-50)/3=10/3 =3.33 lb
C= 80-60 /3=20/3 =6.66 lb
Answer:
2nd option
Step-by-step explanation:
the scale factor is the ratio of corresponding sides, image to original, so
scale factor =
=
=
= 1 
600 becuase 90/.30= 300 and 300*2 =600
Flip should get 4 boxes.
6*5=30
30/8=3.75
round up for 4.
