O 6N + 12N = 40
O 6N + 12 = 40
6(N + 12) = 40
Answer:
6(N + 12) = 40
Step-by-step explanation:
Number = N
Sum of a number and twelve:
N + 12
Six times the sum of a number and twelve:
6(N + 12)
Six times the sum of a number and twelve is forty:
6(N + 12) = 40
Answer:
6(N+12) = 40
Step-by-step explanation:
The statement says six times the sum . . .
From this we can tell that the answer will be 6 times two numbers added together. Those two numbers are "a number" (some variable) and 12.
We can tell that the variable is N, so it answer must be 6(N + 12) = 40
Answer: 1.75p

Let 'p' represents the current population.
The increase in the population of the city =7.5%
Therefore, the expected population next year= Current population+75% of the current population
Hence, the expected population next year= 1.75p

Answer:
7,000 calories or 7 kilo cal/min.
Step-by-step explanation:
Lucia is using energy at a rate of 420 kilo calories per hour ice skating.
1 kilo calories = 1000 calories
420 kilo calories = 420,000 calories
1 hour = 60 minutes
∵ Lucia is using energy per 60 minutes = 420,000 calories
∴ She is using energy per minute =
= 7,000 calories or 7 kilo calories
Lucia is using energy 7,000 calories/minute.
