Ethan's mistakes in sorting the shapes into two groups are:
- Shape C does not belong to group 1 because it does not have square corners
- Shape F does not belong to group 2 because it does not have any square corners
<h3>How to spot the mistakes?</h3>
From the complete question (see attachment), the shapes are grouped using the following criteria:
- All the shapes in group 1 have 4 square corners
- All the shapes in group 2 have exactly 1 square corner
Using the above rules, Ethan's mistakes are: shapes C and F are placed in the wrong groups

Answer:
5(2x-3)
Step-by-step explanation:
Well, we first know that Dominic uses 1/2 tablespoon. So if we use that 1/2 tablespoon on two sandwiches how many tablespoons does Dominic use? A whole! If you make another two sandwiches, then it will make another whole, and I whole plus one whole equals two wholes. Then, you make another one which uses another 1/2. And 1 whole plus one whole plus 1/2 a tablespoon equals 2 1/2!
Answer:
2.5 hours
Step-by-step explanation:
<em>Let t = time in hours for reach friend's house
</em>
<em>(t-1.5) = time for friend to drive her home
</em>
:
Both trips are the same distance, Write a distance equation from this fact:
<em>Distance = speed * time
</em>
<em>Drive distance = Bike distance
</em>
<u>Equation-</u>
<u>step1)</u> 25 (t-1.5) = 10t (here u multiply 25 by t and 25 by 1.5)
<u>step2</u>) 25t - 37.5 = 10t (move 37.5)
<u>step3)</u> 25t - 10t = +37.5 (subtract 25t from 10t)
<u>step4</u>) 15t = 37.5 (divide 37.5 by 15)
<u>step5</u>) t = 2.5 (time it took Luke to reach his aunt's house)
