The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17:

Step 1: 5x − 2x − 3 = −2 + 17
Step 2: 5x − 2x − 3 = 15
Step 3: 3x − 3 = 15

Which of these is most likely the next step?

Answers

Answer 1
Answer: The next step is most likely to add 3 to both sides, so that 3 cancels out, and 15 turns into 18.

The answer is: Step 4: 3x = 18
(I don't know if you want me to continue or not, but I will) ;)

Then divide by 3 on both sides so that 3 cancels out and 18 turns into 6, and you have the value of x. 

Step 5: x = 6

You can check your answer by replacing x with 6.

5 · 6 - 2 · 6 - 3 = -2 + 17
15 = 15

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Kiera's dance class starts at 4:30 p.m. and ends at 6:15 p.m. How long is her dance class?

Answers

Her dance class is 1 hour and 45 minutes.

This is because there is 1 hour from 4:30 to 5:30. Then, there is 45 minutes from 5:30 to 6:15

Good luck!
If Kiera's dance class starts at 4:30 p.m. and ends at 6:15 p.m. then how long is it? Lets find out. The way I solved it would be to count by hours. 4:30 to 5:30 is one hour. 5:30 to 6:30 is 2 hours. But 6:30 is too much time. So now you take away the required amount to make it 6:15. You have to take away 15 minutes. So 2 hours minus 15 equals 1 hour and 45 minutes. 
Kiera's dance class was 1 hour and 45 minutes long.

Which of the following is not true about genes?They are passed down from your ancestors.

They contain instructions for your physiology and behavior.

Some people are born with an entirely new set of genes not seen in their parents.

Some parts of your genes can become different from your parents as you are forming.

Answers

The answer is C. Some people are born with an entirely new set of genes not seen in their parents. (This one is not true because we do see genes inherited/seen from our parents. For example, if our parents have brown eyes, we can have brown eyes, or same thing with hair, if our parents have brown hair, we can inherit/ be seen having brown hair just like them, we inherit genes similar to our parents because they made us, in turn, they gave us some of their features and genes.)
