Answer:
- 7227
- 6649
Step-by-step explanation:
Let x represent the enrollment the first year. Then x(1 -8%) = 0.92x represents the enrollment the second year. The total for the two years is ...
x + 0.92x = 13,876
x = 13,876/1.92 = 7227.083 ≈ 7227 . . . . students the first year
13876 -7227 = 6649 . . . . students the second year
It’s the first choice: communities property of addition
Answer:
area is length * width, so
5x10^5 * 4x10^4
multiplication is commutative, so that's
5*4 * 10^5*10^4
= 20 * 10^9
= 2*10^10 m^2
if the powers stuff is confusing, it's just shorthand for multiplication
10^5*10^4 = (10*10*10*10*10)*(10*10*10*10) = 10^9
just as multiplication is shorthand for addition
5*4 = 5+5+5+5
