Answer:
Option C.
Step-by-step explanation:
We need to translate each phrase and find the different expression.
"+" sign is used for sum, more and total.
Twice means two times of a number.
Let n be the unknown number.
Two more than a number = n+2
The total of n and 2 = n+2
Twice the number n = 2n
Sum of n and 2 = n+2
From the above expressions it is clear that only 2n is different from other.
Therefore, the correct option is C.
In this question, we have to convert 12m/s to km/min .
And for the conversion, we need km in the numerator and min in the denominator .
And 1 km equals to 1000 m and 60 seconds equals to 1 minute .
And that's the required conversion factor to convert 12m/s to km/min.
And hence out of the four given options, correct options are A and B .

Please, proofread your problem statements before posting them. Your "If 1,600 people live 25% of the population how many people need to leave" should be written as "<span>If the whole population is 1,600 and 25% of them need to leave, how many must leave?"
0.25(1600) = 400
400 people need to leave. This is 25% of the entire population, or 25% of 1600 people. Please note: it's "leave," not "live."</span>
Answer is 1/2.
Explanation:
We can divide 1 pizza up into 4 x 1/4.
So, 2 pizzas would mean 8 x 1/4.
However, if there is only 2 x 1/4, that would mean that it is half of 1 pizza. So,
2 x 1/4 = 1/4
