Which best describes the error that Mia made when solving the equation?

Answer 1

Answer:

Mia multiplied one side of the equation by 5/3 and the other side by 3/5. This makes the equation unbalanced and untrue. x should be 50

Step-by-step explanation:

Answer 2

The second step existed incorrect and the total time allotted was: 50 minutes.

Calculation of time allotted

Let the total time allotted be x minutes.

Mia spent 30 minutes answering the math questions on the exam. This existed $3 / 5$ of the total amount of time allotted for this section of the exam.

The first step was accurate i.e.

$\frac{3}{5} x=30$

Now, on multiplying both sides by $5 / 3$,

$\frac{5}{3} \times \frac{3}{5} \times x=30 \times \frac{5}{3}$

x=50

Therefore, the second step existed incorrect and the total time allotted was: 50 minutes.
