mezya [45]

Answer:

Maggie is incorrect.

Step-by-step explanation:

PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 <em>before</em> dividing.

I hope this helps!

“Ms. Blanco drove her car at a speed of 80 kilometers per hour for 1 1/2 hours, then at a speed of 100 kilometers per hour for 2

and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour
