Question

Mia tried to solve an equation step by step.
0.1t - 3 = 5

Step 1: 0.1t = 2

Step 2: t = 20

Find Mia’s mistake.
A. Step 1
B. Step 2
C. Mia did not make a mistake.

Answer 1

Answer:

step 1 is incorrect

0.1t = 8

t=80

Answer 2

Answer:

Step 1

Step-by-step explanation:

Equation: 0.1t - 3 = 5

How to solve:

1. Add three to both sides to cancel out the negative 3, which will give you the following: 0.1t = 8
2. Already we know that Mia made a mistake. The problem says step one should look like this: 0.1t = 2, and that's not what we got.

Therefore, Mia made a mistake in step 1.
