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.
Answer:
5x-5y
Step-by-step explanation:
P=presne amount=5000
A=furutre amount which you want to be 5304.50
solve for r
5304.50=5000(1+r)^2
divide both sides by 5000
1.0609=(1+r)^2
sqrt both sides (remember to get positive and negative roots)
+/-1.03=1+r
minus 1 both sides
+/-1.03-1=r
+1.03-1=r=0.03=3%
-1.03-1=r=-2.03=false, no negative percents
answer is 3%
