You read 50 pages in an hour. Your sister reads 40 pages in an hour. Explain how to find out how many more pages you read than your sister reads in 1/2 hour?A. I know that 50 • 40 = 2,000, so I read 1,000 more pages than my sister reads in 1/2 hour.
B. I know that 50 ÷ 40 = 5454, 5 ÷ 4 = 1 1/4, so I read 1 1/4 more pages than my sister reads in 1/2 hour.
C. Because I read 10 more pages than my sister reads in 1 hour, I read 5 more pages in 1/2 hour.
D. Since 5 • 4 = 20, I read 20 more pages than my sister reads in 1/2 one half hour.

Final answer:
The number of registered cars in the US increased by about 231.76% from 1950 to 1990, calculated by finding the difference between the two given values, then dividing this by the initial value and multiplying by 100 to get the answer as a percentage.
Explanation:
The question is asking for a percent increase in the number of registered cars in the United States from 1950 to 1990. To calculate a percent increase, you first need to determine the amount of the increase, then divide this by the original amount, and multiply by 100 to get the answer in percent form.
The number of registered cars in the United States increased from 40.3 million in 1950 to 133.7 million in 1990. The amount of increase is therefore 133.7 (1990 number) - 40.3 (1950 number) = 93.4 million.
Next, we find the percent increase by dividing the increase by the original (1950) amount and multiplying by 100: (93.4 / 40.3) x 100 = Approximately 231.76%. So, there was roughly a 231.76% increase in the number of registered cars in the United States from 1950 to 1990.

5n + 34 = -2 (1 - 7n )
Answers
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
