Question

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. If 30 states joined the United States between 1776 and 1849 and x states joined between 1850 and 1900, which of the following equations is true?

Options

A)
30x = 2
B)
2x = 30
C)
\(\frac{x}{2}\) = 30
D)
x + 30 = 2

The correct answer is B.

Explanation:

Choice B is correct. To fit the scenario described, 30 must be twice as  large as x. This can be written as 2x = 30.

Choices A, C, and D are incorrect. These equations do not correctly relate the numbers and variables described in the stem. For example, the expression in choice C states that 30 is half as large as x, not twice as large as x.
