Answer:
6(a - 5)(b - 2)
Step-by-step explanation:
60 + 6ab - 30b - 12a
Factor out the common term 6:
= 6(10 + ab - 5b - 2a)
Rearrange:
= 6(ab - 2a - 5b + 10)
Factor:
= 6(a - 5)(b - 2)
Answer:
Nickel= 1.8 kg
Zinc= 0.4 kg
Copper= 1.8 kg
Step-by-step explanation:
7:2:9
7=nickel
2=zinc
9=copper
7+2+9=18
18×2=36
7×2=14 2×2=4 9×2=18
Divide by 10
14÷10=1.4 4÷10=0.4 18÷10=1.8
1.8+1.4+0.4= 3.6
1.8=nickel
0.4=zinc
1.8=copper
Divide the volume value by 1000, which is 0.194 .
