Answer:
The total weight of the metal bar in pounds is 25 pounds 
Step-by-step explanation:
Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.
Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc 
Mathematically;
60/100 * x = 15
60x = 15 * 100
60x = 1500
x = 1500/60
x = 25 pounds

Answer:
9 students in music class.
Step-by-step explanation:
In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.
 4 x _ = 12. —> 4 x 3 = 12. 
so we need to do the same for music class.
For music there are 3. 
so we multiply by 3 like we did with the 4. 
3 x 3 = _ —> 3 x 3 =9. 
so there are 9 students in music class.
