Answer: b. 2x = 30

Step-by-step explanation:

Given : 30 states joined the United States between 1776 and 1849

and x states joined between 1850 and 1900.

If the number of states that joined the United States between 1776 and 1849 is twice the number of states that joined between 1850 and 1900.

i. e. No. of states joined the United States between 1776 and 1849 = 2 (No. of states that joined between 1850 and 1900)

i. e. 30 = 2 (x) [Substitute the values]

i. e. 2x=30

Hence, the true equation : 2x=30
