30 × 100 = 3,000, 30 × 10³ = 30,000 and 30 × 1000 = 30000. Therefore, options A, B, C and D are the correct answers.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
A) 30 × 100 = 3,000
Here, LHS = RHS
B) 30 × 10³ = 30,000
Here, LHS = RHS
C) 30 × 1000 = 30000
Here, LHS = RHS
D) 
30 × 10000 = 300,000
Here, LHS ≠ RHS
E) 30 × 10000 = 30,000
= 300,000
Here, LHS ≠ RHS
Therefore, options A, B, C and D are the correct answers.

Answer:
what are the choices
Step-by-step explanation:
The correct answer is:
B)15h+135≥575
We can calcutate with this inequality (15h+135≥575) the minimun number necesary of hour that Samantha have to work for buy the plane ticket.
15h+135≥575
15h≥575-135
15h≥440
h≥440/15
h≥29.333 then h≥30
Samantha need work greater tan or equal to 30 hours.
To chek:
h=29 ⇒15(29)+135=570<575
h=30 ⇒15(30)+135=585>575; therefore h≥30
I think It would be no because theres not reason for the 3 miles to your friends house to be negative
