Answer: b. 2x = 30
Step-by-step explanation:
Given : <u>30 states</u> joined the United States between 1776 and 1849
and <u>x states</u> 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
Answer:
1,3,17 this is answer I pulled it up
Step-by-step explanation:
<h3>Part A</h3>
At least 30 miles but less than 50 miles each week.
<u>Required inequality:</u>
<u>In 4 weeks:</u>
<h3>Part B</h3>
- "At least" means equal or more than 30, hence 30 ≤ x
- Less than 50, hence x < 50
<h3>Part C</h3>
At least 8 but no more than 12 gallons of gas each week, with the cost $2.25 to $2.50 per gallon.
