Answer: 19 minutes
Step-by-step explanation:
Here is the complete question:
takes Andrew 720 seconds to take a shower. He spends an additional 420 seconds eating breakfast.
How many minutes does it take Andrew to take a shower and eat breakfast?
From the question, we are told that Andrew spends 720 seconds to take a shower and also spends an additional 420 seconds eating breakfast. The total time spent by Andrew will be:
= 720 seconds + 420 seconds
= 1140 seconds
We will then convert 1140 seconds to minutes. We should note that 60 seconds = 1 minute. Therefore,
1140 seconds = 1140/60
= 19 minutes
Andrew uses 19 minutes to take a shower and eat breakfast.
Students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).
Given the equation solved by a student
10x−3+2x=6(x−3)
- The first step that the student could use to solve the expression correctly is to expand the bracket on the right-hand side of the equation using the distributive law as shown:

- The student can also combine like terms on the left side of the equation, to give;

Hence the correct option will be students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).
